What is 8ct Gold?
8ct gold is composed of 8 parts pure gold out of a total of 24, making it approximately 33.3% pure. This purity level is often stamped as “333” on jewellery to indicate its composition. Compared to higher carat golds, 8ct gold has a darker, slightly more 'brassy' tone to its colour, due to the higher proportion of copper.
Variants of 8ct Gold
8ct gold can be alloyed (mixed) to create different colours:
- Yellow Gold: Traditional and hypoallergenic, achieved by adding metals like copper, zinc and silver.
- White Gold: Alloyed with zinc and silver, whilst omitting the copper. White gold is often rhodium-plated for brightness but requires re-plating over time.
- Rose Gold: Alloyed with more copper and less zinc and silver to create a pink hue.
