21k jewelry vs 22k jewelry: Gold purity

The purity of gold in jewelry is measured in karats, with 24 karat gold being 100% pure gold. Both 21k and 22k gold jewelry are made of real gold, but there is a difference in their purity levels.

21k gold has a purity level of 87.5%, meaning that it contains 21 parts gold and 3 parts of other metals such as copper or silver. This makes it less pure than 22k gold.

22k gold has a purity level of 91.6%, meaning that it contains 22 parts gold and 2 parts of other metals. This higher purity level results in a richer, deeper yellow color and a softer, more malleable texture.

The higher the gold content, the more valuable the jewelry tends to be. However, the higher the purity, the softer the gold becomes and the more prone it is to scratches and dents. For this reason, 21k gold jewelry may be a better choice for jewelry that will be worn frequently or for pieces that require greater durability, while 22k gold may be more suitable for special occasion pieces.

It's important to note that both 21k and 22k gold are valuable and can make beautiful jewelry, and the choice ultimately comes down to personal preference and the specific needs of the wearer.
