International Gold Karat
Gold karat is a measure of the purity of gold, expressed in parts per 24. The higher the karat number, the higher the percentage of gold in the alloy.
International gold karat standards were established by the World Gold Council in 1972. The most common karatages are 24K, 18K, 14K, and 10K.
* 24K gold is pure gold, with no other metals added. It is very soft and easily damaged, so it is not often used in jewelry.
* 18K gold is 75% gold and 25% other metals. It is a good choice for jewelry because it is hard enough to withstand wear and tear, but still retains the rich color of gold.
* 14K gold is 58.3% gold and 41.7% other metals. It is a more affordable option than 18K gold, but it is still considered to be a high-quality metal.
* 10K gold is 41.7% gold and 58.3% other metals. It is the least expensive type of gold jewelry, but it is also the least durable.
In addition to the international gold karat standards, there are also regional standards that may differ slightly. For example, in the United States, 10K gold must be at least 41.7% gold, while in Europe it must be at least 37.5% gold.
When purchasing gold jewelry, it is important to know the karatage of the metal. This will help you to assess the quality and value of the piece.
