Gold Jewellery Everything You've Ever Wanted to Know About Gold Jewellery The purity of gold is calculated in carats The word 'carat' (or karat) comes from 'kertion', which is Greek for "carob seed'. It was originally used as a unit of weight in classical times. Most jewellery falls between the range of 10K (41.7% pure gold), and 18K (75% pure gold). The purest gold is 24K. This is usually not used for jewellery because it is too soft and malleable. High purity gold (22K 24K) is much more popular in Asia than it is in Europe or the US.
