International Gold Markings on Jewelry
Gold is a precious metal that has been used in jewelry for centuries. To ensure the authenticity and quality of gold jewelry, international markings are used to indicate its purity and fineness. These markings vary from country to country, but they all provide important information for consumers.
Karat
The karat is a unit of measurement used to indicate the purity of gold. Karat is abbreviated as “K” or “kt.” Pure gold is 24 karats, but most gold jewelry is not pure gold. Gold is usually alloyed with other metals, such as copper or silver, to make it more durable and harder.
The most common karatage for gold jewelry is 14K, 18K, and 22K. 14K gold is 58.3% pure gold, 18K gold is 75% pure gold, and 22K gold is 91.6% pure gold.
Fineness
Fineness is another way to indicate the purity of gold. Fineness is measured in parts per thousand, so pure gold is 1000 parts per thousand.
The most common finenesses for gold jewelry are 583 (14K), 750 (18K), and 916 (22K).
Hallmarks
Hallmarks are small marks that are stamped on gold jewelry to indicate its purity and origin. Hallmarks typically include:
* The karat or fineness
* The manufacturer’s mark
* The country of origin
* A unique serial number
