Modern uses of gold

Since the time of our most ancient civilisations, we have used gold to decorate our bodies and our most precious objects, and to make coins and currencies around the world. 

In today’s society, the gold in our coins have been replaced by metals like copper and nickel that only look gold-coloured. However, we still like to ornament ourselves with this precious metal. The vast majority of gold produced and used each year continues to be made into jewellery, from wedding rings to gold watches to tiaras. However gold has many more uses and roles to play in our twenty first century world.

The art of gold

The beautiful sheen and shine of gold has long been used to embellish and produce works of art and craft. Gold can be made into a powder, mixed with paint and used to create pictures. Medieval scribes used this method to make illuminated manuscripts and applied gold to highlight the lettering and borders in hand written books.

The ability of gold to be hammered into thin sheets called gold leaf makes it easy for artists to apply it to objects. It is also much less costly to apply a layer of gold rather than making a solid gold object. Modern artists like Jeff Koons continue to use gilding in their works such as his provocative sculpture of Michael Jackson and Bubbles.


Gold is highly ductile – that means it can be beaten to a thinness of 1/282,000 inch and pulled into fine threads. European goldsmiths in the twelfth century made cloth of gold for members of royalty and the aristocracy. Gold continues to be used in our modern fashion industry, especially for the most glamourous outfits and events. Gold lamé is made from thin strips of metallic fibre woven or knit into fabric. It reached the height of its popularity in 1930s Hollywood when actresses wore gold lamé gowns on the screen during the Great Depression. Ironically the audience couldn’t see the colour as the films were made in black and white – but the dresses still had an amazing sheen and flow on camera.

In the Middle Ages people thought that gold had miraculous powers. They believed that if they could find the right recipe for a drink made out of gold, it could act as an elixir of youth.  Noblewomen like Diane de Poitiers in the sixteenth century drank ‘potable’ gold to try to stay young. Unfortunately consuming gold in large quantities can be toxic.

When the remains of her hair was tested in 2009, tests found traces of gold chloride and diethyl ether, suggesting that de Poitiers died of chronic gold poisoning.

In modern medicine small amounts of gold can be prescribed as a remedy. Sufferers of rheumatoid arthritis can use a gold compound as an anti-inflammatory. Doctors are currently researching the use of tiny gold fragments known as nanoparticles in new cancer treatments.

As gold is nonreactive and resistant to bacterial infections, it is used in implants for the inner ear and pacemakers as well as some medical equipment such as surgical tools and life support devices.

However, the main medical use of gold is for dentistry. This is nothing new.  Records from 700 B.C. show the Etruscans used gold wires to create dental bridges. Gold was used to make false teeth because it could be easily shaped and was biocompatible – meaning it doesn’t cause a reaction when placed in a human body. Some people and cultures have also used gold teeth as a visible sign of their wealth.

Today, gold is mainly used in dentistry for bridges, fillings, crowns, and orthodontic appliances because it still lasts longer than other dental materials. What was once medical necessity has become a fashion for some. Grillz – false teeth covers made of metal – are popular in hip hop culture and worn by celebrities like Miley Cyrus and Madonna.

Gold and food

Whilst eating gold is not going to cause any tooth decay, it will not provide any nutritional value either. Edible gold is a special nontoxic form of the metal which actually costs more to produce than non-edible gold. It has no taste or texture and will not be absorbed by the body.

Gold covered ice cream

However in Japan, there is a growing trend for consuming gold. The city of Kanazawa produces 98 percent of all gold leaf in Japan. One of the most popular tourist activities there is trying food and drinks covered with thin gold sheets and flakes. Visitors can sample gold-topped ice cream, shakes and even sushi.

In the UK you can buy Goldschlager cinnamon schnapps which has floating flakes of 24 carat gold. Some London restaurants have also created extravagant dishes with edible gold such as the Bombay Brasserie in Kensington. Its Samundari Khazana curry, meaning ‘seafood treasure’, included Beluga caviar-fllled cherry tomatoes wrapped in gold leaf.


Our modern world has found different uses for gold. Indeed much of our society relies on it. The unique properties of gold have aided the development of new technology such as the transistor and the microchip.

Transistors are a type of electronic switch. They act as a semiconductor device used to amplify or switch electronic signals and electrical power. One of the first transistors invented was made out of two gold foil contacts sitting on a germanium crystal. Microchips are made up out of transistors. They act as small units of computer circuitry used for computer memory or program logic.

Both transistors and microchips contain a fine gold wire to connect the different components and make connections. Electronic voltages and currents are easily interrupted by metal that corrodes or tarnishes. Therefore a small amount of gold is used in many electronic devices because it’s impervious to humidity or corrosion.

The invention of the transistor and microchip have transformed the world of electronics and computer design. Our mobile phone’s connectors, switches and relay contacts all contain gold. Both desktop computers and laptops contain gold in their connectors. Items from alarm clocks to microwaves to televisions, even washing machines contain a little gold. Although we can’t see it, our twenty-first century society depends on the use of the gold in much of our technology.

Space gold

In 1977 the Voyager 1 and 2 space probes were launched. They contained phonograph records constructed out of gold. These records contain greetings, sounds and music to show what life on Earth is like. They are intended as a sort of time capsule for anyone – extraterrestrial life forms or future humans – who may find them. The records were made out of gold-plated copper to best preserve them in the atmosphere of space. The Voyager probes continue to sail on, drifting towards the furthest borders of our solar system. Pic: Cover for the Voyager 1 and 2 “Sounds of Earth” gold-plated records. The diagram on the cover provides the finder with a key to playing the record.

Gold has a particularly useful quality for space travel. It is able to reflect infrared radiation. For this reason it is used on astronaut outfits, especially the visor. Space vessels also have a layer of gold coated polyester which reflects harmful rays and helps stabilize core temperatures inside. The gold in the onboard electronic devices have an added benefit in the vacuum of space as they act as a lubricant between the mechanical moving parts.

James Webb space telescope

In 2020 NASA’s James Webb Space telescope is due to launch into space. The particular quality of gold that makes it so suitable for space use will actually form the basis of this experiment. The telescope’s mirrors are coated with a microscopic gold film that reflects infrared light from space to allow it to be studied by the telescope’s own instruments.

As our technology continues to grow and change, we can’t predict what the future holds in store. One thing we can be certain of however, the unique qualities of gold means it will continue to play many different roles in our society.

Bullion by post

On the face of it, the concept of sending your bullion by post to a remote Internet business like us seems a crazy idea! Hopefully, this article will serve to allay some of your fears and explain how our process works.

Should I send my bullion by post?

We’ve been in business since 2008 and have seen many postal ‘cash for gold’ / bullion dealers come & go. Whilst they always relied on paid Internet advertising and high profit margins (to pay for the advertising), we have steadily grown our business by paying excellent rates, staying small and lean to keep our margins low and offering an exemplary service.

Sending and insuring your bullion by post

The crucial element to a safe and efficient bullion sale is using the correct shipping method. Royal Mail Special Delivery is a very safe and secure method for shipping high value items. Over the 11 and a half years we’ve traded this way, we’ve never had a Special Delivery parcel disappear in transit, and we’ve dealt with thousands of parcels!

An individual Special Delivery can be insured to a maximum value of £2,500. If your coins or bullion amount to a greater value, you may want to consider splitting them across multiple packages. Some customer do this, many don’t.

When you take your package(s) to the Post Office, the counter staff will most likely ask you to disclose the contents. Sending bullion by post is perfectly acceptable, they’re asking to ascertain if you’re sending anything prohibited, such as batteries or blades.

Special Delivery is a guaranteed next day delivery service (Monday to Friday). If you ship a package on a Friday, you’ll be given the option to pay extra for a Saturday delivery, however we suggest you decline this option. Your package won’t be processed until Monday anyway and due to the relationship we have with our delivery office, we’ll likely receive your package on Saturday anyway.

Buying bullion by post

There are many dealers offering the opportunity for you to buy bullion by post. For most customers, price is the deciding factor. As gold is an internationally traded commodity, it’s easy to calculate the base (or ‘spot’) price for a coin or item of bullion.

Incidentally, if you want to know the spot price of a gold Sovereign, take a look here.

What you’re looking for is a dealer who can offer you bullion at the lowest margin over spot. We pride ourselves in offering some of the best prices within the market. Why not give us a call and see if we can meet your requirements?

Trade counter

If, after all our re-assurance, the concept of selling or buying bullion by post is still a step too far, then you still have the option of visiting us to deal face to face. Our trade counter opening hours are from 10.00am to 3.00pm, Monday to Friday and 10:00am to 1:00pm on Saturday.

We look forward to serving you in the near future.

The Science of Gold

Gold is one of the heavy metal elements and comparatively rare. Precious metals like gold, platinum and silver are created when neuron stars crash together. These small but incredibly dense stars contain the huge amount of energy needed to create the metals when they collide. This precious metals are then thrown out into the universe where they combine with other stardust into planets and comets. When our planet was being formed, most of its gold sank into the earth’s core. Scientists estimate there’s enough gold in our planet’s core to cover the whole surface to a depth of 1.5 feet – if we could only reach it.

Gold on our planet

The gold we mine, use and refine in our society comes from surface deposits of gold. These originate from meteorites that crashed into the earth and left the gold behind many eons ago, before all of human history. For example, some of the largest gold deposits in South Africa are estimated to be three billion years old.

Gold is found on every continent although about 40% of all gold was mined at Witwatersrand, in South Africa. Some gold is found in rock formations such as quartz and iron pyrite, and in natural alloys with silver and copper. This is called gold ore. Small particles of gold can also be embedded in rock with other minerals such as pyrite or ‘fool’s gold’ to form a lode deposit.

Gold ore from California

Flakes and nuggets of gold can be found in rivers and streams. These are made up of particles of gold eroded away from rocks. The particles travel down into the water and eventually collect into larger pieces of gold. These are called ‘placer’ deposits from the Spanish word for a sandbank.

Fascinatingly, research has shown that bacteria may also be responsible for creating nuggets of pure gold. Some bacteria have a genetic resistance to heavy metal toxicity and can dissolve gold into nanoparticles. These then travel through sediment and accumulate into nuggets. In fact the largest nuggets ever discovered were found underground in mines. The Canaã nugget is the largest gold nugget currently in existence. It was found in the Serra Pelada mine in Brazil and contains 115.37 lb of gold.

Humans have been mining for gold since the earliest civilisations yet all the gold ever mined in the world could be contained in three Olympic sized swimming pools. It’s thought that there is approximately only another 20 years’ worth of gold left that can be easily mined.

Other sources of gold

Our planet’s oceans contain a huge quantity of gold, approximately 10 – 20 million tons. However the gold is dispersed throughout the waters in tiny amounts of about 1 gram in 100,000 tons of seawater. Many have tried to invent schemes to extract the gold from water. Yet the gold in our oceans remains too difficult and expensive to obtain.

Our bodies also contain about 0.2 milligrams of gold with most of it flowing through our blood.

What are the qualities of gold?

Gold is very stable. This means it doesn’t rust or tarnish like other metals such as silver. Of all the different kinds of metals, gold is the only one that is both coloured and keeps its shine forever. You could bury gold for thousands of years and it would remain un-corroded and shining bright.

Gold is the least reactive of all the chemical elements. It is unaffected by most acids and chemical bases. As a result it is one of the few elements that can be found in its pure natural state. Miners in the nineteenth century knew that gold didn’t react to most other chemicals and used this to test the purity of their finds. They took nitric acid and dripped it onto the metal. If the gold didn’t dissolve or react this showed that it was pure. It is from this practice that we get the phrase ‘acid test’.

Gold can be dissolved with a solution called ‘aqua regia’ first discovered by the alchemists. This is a mixture of nitric and hydrochloride acid that together act as a powerful oxidizer to break the gold down.

Gold is very malleable and soft. It can be beaten out into super-thin sheets, for example a piece of gold about the size of a grain of rice can be beaten flat to cover one square metre. Gold can even be manufactured thin enough to make it semi-transparent.

All of these properties of gold are related to the way the atoms in the gold bond to one another. The strong bonds between the gold atoms stop gold from reacting with other elements and tarnishing. Gold’s molecular structure is held together tightly which creates its malleability and high conductivity. Gold also has very dense and mobile electrons which is why the metal shines when the light bounces off of it.

What is pure gold?

The carat system is commonly used to describe how pure gold is. 24 carat gold is considered to be unadulterated gold. 18 carat gold is 75 % gold or 18 parts gold with 6 parts formed of another metal. In actual practice it’s impossible for gold to be completely 100 % pure but the amount of acceptable impurity is very small at 0.01 %. The absolute purest known sample of gold was produced at the Perth mint in Australia and was confirmed to be 999.999 % pure gold.

Different carats of gold

The word carat comes from the Arabic name for the seed of the carob tree. In the days before standardised measurements, the carob seed was used to weigh gold because people believed the seeds all weighed the same – although this wasn’t actually true. One pure gold coin was considered to weigh the same as 24 carob seeds and so 24 carat gold was used as a measurement of 100 % gold.

Gold alloys

Gold can be melted and mixed with other metals or chemicals to form an alloy. This gives the alloy characteristics of both substances. Gold, for example can be combined with another metal to strengthen it and make an alloy that is tough enough for everyday use.

Ancient civilisations such as in Egypt and Greece knew how to make gold alloys. They mixed gold with other metals to create brightly coloured alloys for jewellery and decoration, such as iron and gold which combined to make a vivid burgundy red metal.

Today white gold and rose gold are common alloys. White gold is a combination of gold and white metal such as silver, palladium, platinum and nickel. A nickel and gold mix makes the alloy strong and hard whereas platinum and gold produces a heavy and durable alloy.

Rose gold is made from gold and copper. The more copper there is in the alloy, the brighter red it becomes. Rose gold was so popular in Russia during the nineteenth century that it became known as Russian gold.

Gold can be mixed with other metals and chemicals to produce alloys ranging in colour from black to blue, grey, green and purple.

The nature of gold means that it’s quite easy to separate it from an alloy. As gold is unreactive, a gold alloy can be heated with salt to make the other metals burn away or be absorbed to leave the pure gold behind.

Synthetic gold

It is possible to create artificial gold. In 1924 a Japanese physicist produced gold from mercury by bombarding it with neutrons – but the gold was radioactive. Since then experiments have included using a particle accelerator to transform bismuth to gold, and irradiating platinum and mercury in a nuclear reactor.

The problem is that gold is produced by immense amounts of energy and heat from the fusion of dying stars. We could replicate some of those conditions using a supercollider but it would be too expensive and take too long to produce enough metal for it to be a feasible source of gold.

The reclamation of gold

There is an alternative source of gold to mining or artificial experiments. The reclamation of previously used gold is an increasing source of the metal. As well as for jewellery, gold is often used in the electronics industry. The properties of gold such as its high conductivity and lack of tarnish mean it is used in circuit boards and wiring. As a result obsolete electronic devices such as computers and mobile phones are now a substantial source of recoverable gold. For example in 2015 Apple obtained over 2000 lbs of gold from broken iPhones.

It is now both profitable and more environmentally friendly to recycle the gold that has already been in use, rather than extract fresh gold from mining into the earth.

The history of alchemy and the search for gold

Alchemy is most well-known for its attempts to change common metals into silver and gold. Yet is an ancient discipline originally studied in Egypt and the Greek Hellenistic empire, China and India. 

The origins of alchemy

Alchemy came to Western Europe from the Islamic kingdoms in the twelfth century. Arabic alchemical books were initially translated by the Christian church. Its ideas of transmutation became increasingly popular. Interest in alchemical gold peaked between the sixteenth and eighteenth centuries at a time of numerous famines and wars and a great need for money to fund them. Yet alchemy was more than just a fantastical get-rich-quick scheme. It combined ideas from early science and medicine with religious and metaphysical beliefs.

17th centre alchemy book

This seventeenth century alchemical book was attributed to Geber, the Latinised version of Jabir ibn Hayyan, an Islamic alchemist in the ninth century.

Alchemists wanted to change one thing into another. In order to do this, practitioners first had to think about what their substances were made up of and how they could alter them. In the days before modern science, alchemy was one way to think about the world and try to understand how it worked. By the late sixteenth century alchemy was regarded as a serious scientific and philosophical pursuit, despite its controversial nature. Leading scientific thinkers of the day such as Robert Boyle and Isaac Newton studied alchemy. Newton wrote more than a million words about it.

Theories of alchemy

There was no schools or guilds of alchemists with authorised teachings. This meant that there were many different theories and ideas about how alchemy worked.

Alchemists believed that everything was made up of the four elements of earth, air, fire and water. This was originally a Greek idea, from the philosopher Aristotle, who also believed that the universe was divided into two parts – heaven and earth.  What happened in heaven was reflected on the earth below. Alchemists thought the planets were connected to different metals on earth, for example gold was with linked with the sun and its associated properties.

Symbols for metals growing in the bowels of alchemical man

Most people believed that metals were seeded deep into the earth by God when he created the world. Miners noticed that metal ores ran through rocks in veins that looked like plant roots, growing and spreading. Alchemists took this idea a step further. They believed that common metals like iron and lead could develop and mature into silver and then gold as the most perfect of all metals. Alchemists thought they could recreate this process of growth using the Philosopher’s Stone to turn common metals into gold.

The Philosopher’s Stone

Alchemists believed the Philosopher’s Stone had the power of transmutation and could be used to change metal into gold. They called this the ‘Great Work’ or ‘Magnum Opus’. Some alchemists thought the Philosopher’s Stone could also be an elixir or medicine that could extend their life and heal all diseases. They called this ‘potable’ or drinkable gold. Others saw the Philosopher’s Stone as a way to seek enlightenment and a higher spirituality. All they needed to do was find the right alchemical recipe to create it.

Alchemical ingredients

Alchemists used a wide range of materials in their quest for alchemical gold. Books and manuscripts list common ingredients such as metals, minerals like saltpetre and strong acids to dissolve substances so they could be added to the mix. Organic matter might include blood, hair and urine.

Other ingredients are more puzzling. Alchemical recipes often list ‘philosophical’ sulphur and mercury. These were not simply chemicals but somehow embodied certain properties that also needed to be combined to create the Philosopher’s Stone. For example, philosophical mercury was considered to contain female, silver and lunar principles. Alchemists sought to combine both the physical and metaphysical properties in their ingredients.

Common ingredients used in alchemy

This list of alchemical ingredients includes chemicals and metals. It shows both the symbol and the name of the substance in Latin. Aurum is the Latin name for gold.

Alchemical processes 

Once the alchemist had the right ingredients, the next step was to mix them up in the correct combination and then apply several different types of alchemical processes to them. These processes combined alchemical ideas with chemical operations. For example, the first process often involved calcination, which is when material is heated until it’s reduced to ashes. This also reflected the alchemical idea that matter had to be broken down into a basic, primal mass before reforming it into a higher state.

Alchemists used furnaces to control the amount of heat applied to their mixtures and carefully designed vessels and flasks to distil their ingredients by repeatedly boiling and condensing them.

Whilst alchemists couldn’t agree on exactly what processes were involved, most thought that their mixture had to go through several different colour changes as part of the recipe. The first stage produced black matter which then became white as the ingredients were purified.  The heat of furnace was increased to turn the substance red, showing that the alchemist had successfully created the Philosopher’s Stone.

Who practiced alchemy?

In popular culture, alchemists are often shown as wise old men with long beards, labouring away in a dark and smoky laboratory. In reality alchemy was practised by a wide range of people. Some devoted their lives to alchemy and sought rich patrons to fund them. Those who were successful might be rewarded with supplies and equipment. However, if they failed, alchemists could be taken to court or worse. Duke Friedrick of Württemburg (1557–1608) in Germany found it particularly amusing to hang alchemical fraudsters on a gold plated gallows.

Many alchemists were priests and monks. They believed their alchemical work was done with the permission of God and their research revealed the truth of God’s creation. Some alchemists sought the Philosopher’s Stone in order to receive religious enlightenment.

Kings and rulers could see the economic advantage of creating alchemical gold. Some monarchs tried to control alchemy by making it illegal without a special license – granted by them. Others encouraged alchemists to come to their court where they could keep an eye on them, sometimes with unpredictable results. The alchemist Sendivogius’ experiments at the court of Rudolf II in Krakow allegedly set the place on fire causing the King to move to Warsaw, where it became the capitol of Poland.

Alchemists might also be merchants, aristocrats, scholars, doctors, craft-workers, soldiers and cooks. Female authors wrote a number of alchemical books and manuscripts. Noblewomen were patrons and employers of alchemists. Some women used alchemical practices as part of their housekeeping duties.

Knowledge of alchemy was not just limited to its practitioners. Alchemical books and texts became increasingly popular in the sixteenth and seventeenth centuries and so its ideas came to spread throughout literature, theatre and the arts. You can find alchemical themes and ideas in Shakespeare, Chaucer and Milton’s works as well as alchemical images in paintings and architecture.

Symbolism and secrecy

Alchemy was a secret art right from its ancient origins. Texts warned their readers not to share their knowledge because it was too dangerous for the ignorant. So when alchemy arrived in Western Europe, authors continued to write down their recipes using codes and complicated metaphors to disguise their ingredients and practices. This protected their secrets as only another alchemist would be able to understand their words.

As the technology to print text and illustrations improved, alchemical books began to include drawings to accompany their recipes. Alchemists used symbolic images to represent and conceal their ingredients and instructions. These pictures were often a strange mix of emblems from the natural world, mythology and Christianity. They sometimes used startling combinations of sex, death and violence to symbolise chemical processes such as joining ingredients together or the symbolic death of substances into a blackened mass. The final red stage of the Philosopher’s Stone was often shown as a fiery phoenix, resurrected from the dead and able to transform metals into gold.

Mylius, Johann Daniel. Tractatus III Seu Basilica Philosophica. 1618.

The semicircle of birds represent the different stages of alchemical processes. From Mylius, Johann Daniel. Tractatus III Seu Basilica Philosophica. 1618.

The legacy of alchemy

Alchemists continually tried different ingredients, combinations and chemical processes in their quest for alchemical gold. As a result they discovered considerable information about chemicals and other substances. An alchemist named Hennig Brand discovered a new element in his search for the Philosopher’s Stone in 1669. After experiments with the residues from boiled-down urine, Brand found a white substance that glowed in the dark and burnt brilliantly. He named it phosphorus mirabilis meaning miraculous bearer of light. It was the first element discovered since antiquity.

Alchemical knowledge was used in medicine – informing the first uses of chemotherapy – and many other trades such as glass-working, mining and metal-working. However as alchemical beliefs about the structure of matter were disapproved by the first modern chemists, alchemy ceased to be a serious scientific pursuit. However, it has continued to influence our culture in psychology, art, literature and cinema – most notably the Harry Potter films. Alchemy, it seems, continues to transmute and change to remain a part of our society.

Palladium – The alternative to platinum & white gold

Palladium isn’t a new metal; it was discovered back in 1803, and for over a decade has been one of the constituent metals in vehicle catalytic converters. Yet its use in jewellery has been relatively limited until recently. Now palladium is highly valued – Gold Traders currently pays £ for 950 palladium. So what makes palladium so desirable?

Palladium vs. platinum vs. white gold

Palladium is a precious metal with a natural white colour, which is particularly in demand for today’s jewellery trends. In this respect it’s similar to platinum, but as palladium is less dense it costs considerably less.

White gold isn’t truly white. The alloy mix is simply altered to reduce the amount of copper and increase the amount of zinc and silver. Doing so makes the final alloy a more pale yellow colour. To achieve the whiteness, white gold is given a plating of rhodium. Over time, the rhodium plating can wear away, thus revealing the yellow metal underneath.

Ultimately palladium may not have the cachet and exclusivity of gold or platinum, yet it is genuinely a precious metal. With the symbol Pd and atomic number 46, it’s in the same periodic table as platinum and rhodium.

Palladium’s appeal

Palladium’s lower density compared to platinum or gold means it can be used to make jewellery that’s larger with greater visual impact, yet not any heavier. This is a notable advantage for items such as earrings, where heavy pieces can soon feel uncomfortable.

With roughly half the density of platinum and about two-thirds that of gold, palladium is the perfect answer to the present trend for bigger, more conspicuous pieces. Its white colouring adds to its appeal – couples who like the look of platinum wedding rings but find them unaffordable, are often happy to have them made from palladium, with the end result looking remarkably similar.

Palladium characteristics

Back in the 1930s, palladium was mostly used as an annealing alloy to turn gold white. Subsequent technical advances in casting have seen this precious metal increasingly used in its own right, for its unique qualities.

Once annealed, palladium is soft and easy to work, yet it hardens more quickly than other precious metals. It has no ‘memory’ – in other words, once set, it retains its new shape without trying to spring back to its original form. Palladium has the lowest melting point of the platinum group metals to which it belongs (the others are platinum, rhodium, ruthenium, iridium and osmium), and temperatures above 400°C can cause discolouration, so jewellers are careful in their use of heat when working with it.

A cost-effective alternative

From early 2000, the price of platinum steadily increased from £175/g ($330/g) to a high of over £1,183/g ($2,270/g). This price rise focused attention on alternative metals, particularly palladium.

As prices for gold and platinum have continued to rise, palladium has become increasingly attractive. The Chinese were quick to develop the market for palladium jewellery, and by mass-producing pieces, have caused palladium values to strengthen. It remains, however, more affordable than gold and platinum.

Future palladium price performance

The consequence of hallmarking is that palladium is now seen as even more respected and desirable, with a resulting increase in demand from jewellers and consumers. In fact, nearly 40,000 palladium pieces were hallmarked in the six months following the introduction of UK hallmarking.

With an increasing demand for palladium jewellery, and its continuing use in catalytic converters, electronics, aviation components, dentistry and even musical instruments, the value of palladium will at the very least be stable. The most likely outcome is that the relatively small annual supplies, which are prone to political disturbances, will make palladium more valuable – literally a precious metal.
