What Does the "K" Mean When Referring to Gold?

The “K" in 10K and 14K gold refers to the karat of gold.

The term "karat" (K) designates the amount of gold found in a piece of jewellery.  

Pure gold is 24K and signifies 99.9 percent purity, the highest you can buy.  Pure gold is very soft.

Jewellery is often made in 10K, 14K or 18K.  These indicate the content of gold per karat.

10K gold is 41.67% gold

14K is 58.33% gold

18k is 75% gold. 

Gold is mixed with other alloys to produce a harder, more workable metal that can be used for making jewellery.
