International Gold Karat
Gold karat is a measure of the purity of gold. Karat is derived from the Arabic word qīrāt, which means “carob seed.” In the Middle Ages, goldsmiths used carob seeds to weigh gold. One karat is equal to 1/24th of the total weight of the gold alloy. Pure gold is 24 karats.
The international gold karat system is used in most countries around the world. The following table shows the karat and purity of gold:
| Karat | Purity |
|—|—|
| 24 | 100% |
| 22 | 91.67% |
| 21 | 87.50% |
| 18 | 75.00% |
| 14 | 58.33% |
| 10 | 41.67% |
The higher the karat, the purer the gold. Pure gold is very soft and malleable, so it is often alloyed with other metals to make it stronger and more durable. The most common metals used to alloy gold are copper and silver.
Gold karat is an important factor to consider when purchasing gold jewelry. The higher the karat, the more valuable the jewelry will be. However, higher karat gold is also more expensive. It is important to choose a karat that fits your budget and needs.
Here are some tips for choosing the right gold karat:
* If you are looking for an investment, choose 24 karat gold.
* If you are looking for durable jewelry that will last a lifetime, choose 18 karat or 22 karat gold.
* If you are on a budget, choose 14 karat or 10 karat gold.
No matter what karat you choose, gold is a beautiful and valuable metal that will always be in style.
