Gold purity refers to the actual amount of pure gold that is present in a piece of jewelry. Pure gold is too soft to stand alone in some types of jewelry. So other metals such as nickel, copper, silver, and zinc are alloyed with it to make it stronger and more durable. It is then given a Karatage, denoted by the letter “k”, to indicate the level of purity. Karatage is rated in 24ths, so 24K would be 100% pure gold. A piece of gold that is 18K is 75% gold, 14K is about 58%, and 10K is 41.7%.

The different types of alloy metals are also what contribute to the different colors of gold, like yellow, white, and rose.

  • Yellow Gold — An expert mixture of copper, silver and pure gold gives this precious metal its signature warmth.
  • White Gold – White gold looks similar to silver, but with a richer appearance. It is due to the rhodium that is alloyed with the gold.
  • White Gold with Black Rhodium — Black rhodium is plated to white gold creating a rich black appearance that is extremely hard and strong.
  • Rose Gold — The beautiful pink hue of rose gold jewelry is created by using a copper alloy.
  • Vermeil — Vermeil is a combination of sterling silver, gold, and other precious metals, commonly used as a component in jewelry.
