Breaking the Gold Code: 22K 18K 14K 10K


Houston Jewelry Appraiser Jewelry Judge Ben Gordon - Gold ServiceA gold karat is a unit of measurement that identifies its purity.  100% gold is soft and malleable and would be impractical as jewelry as it would become distorted and wear quickly.  Other metals such as copper, silver, zinc, and nickel are therefore mixed with gold to strengthen it.

What percent is gold and what percent is other metals?

Here is a simple guide to the meaning of 22K, 18K 14K and 10K gold – the most popular gold purity indicators found in fine jewelry.

The gold bars at Fort Knox are 24 karat gold, the purest gold possible. There is no such thing as 25 or 26 karat gold, so steer clear of anyone who makes such a claim.  Most gold jewelry sold today is stamped to indicate the karat value, but often a stamp is illegible or worn away.  The Jewelry Judge can test to identify the karat weight of gold as well as platinum and silver.
