20k gold is a type of gold that is found in some vintage jewelry items. It can be found in old chains, rings, and earrings. Below we'll provide more detail about this gold type and how much it can be worth.

What Is 20K Gold?

20k gold is real gold with a high purity. 20k refers to the gold's level of purity, and it means that your item is 20 karats out of a maximum of 24 karats. It's composed of 83.3% gold and 16.7% alloy. 20k gold is the same as 833 gold.

This type of gold was common in past eras. In modern times 20k gold is hardly ever made. Instead, 18k gold or 22k gold are the standard options for this level of purity.
