When jewelers just use the word “gold”, they are often talking abut solid gold. Solid gold’s name can be misleading… It is not 100% gold element. In the purest form (24k), gold is soft, almost an orange color, and much too weak to work with for jewelry. Because of this, alloys are added to create a stronger, more structurally sound metal that is known as “solid gold”. Not all solid gold has equal proportions of gold. 14k gold has 14 parts pure gold and 10 parts other alloys, whereas 18k gold is 18 parts gold and 6 parts alloys.
