Karat, typically seen as a “K” following a number, shows how much gold is in a piece of jewelry. Jewelry is almost always made with an alloy, meaning a combination of metals, because pure gold is easily scratched, dented or even bent. The number before the K indicate how many parts out of 24 are gold. Gold marked 14K is made of 14 parts gold and 10 parts other metals. If you think of it as a ratio, you get 14/24. With a little math (divide 14/24), we find that 14K is 58.5% gold.
