What is the difference between carat weight for diamonds and for gold?
In terms of gold the carat weight refers to the amount of gold present out of 24 “parts” available. Therefore 18 carat gold has 18 parts pure gold and 6 parts other metals. In White Gold the other parts are mainly silver which gives its colour. In Diamond terms, carats denotes the weight in the same way that ounces and pounds apply to sugar.
