International Gold Karat Scale
The international gold karat scale is a system used to measure the purity of gold. Karat (abbreviated as “K” or “kt”) is a unit of measurement that represents the parts of pure gold in 24 parts of an alloy. Pure gold is 24 karats, which means that it contains 24 parts of gold and no other metals.
The karat scale ranges from 1 to 24, with each karat representing 1/24th of pure gold. For example, 18 karat gold is 75% pure gold and 25% other metals, while 12 karat gold is 50% pure gold and 50% other metals.
The international gold karat scale is used worldwide to ensure that the purity of gold is accurately represented. It is used by jewelers, banks, and other institutions to determine the value of gold and to ensure that customers are getting what they pay for.
The following table shows the karat scale and the corresponding purity of gold:
| Karat | Purity |
|—|—|
| 24K | 99.9% |
| 22K | 91.6% |
| 18K | 75% |
| 14K | 58.3% |
| 12K | 50% |
| 10K | 41.7% |
| 9K | 37.5% |
It is important to note that the karat scale is only a measure of purity. It does not indicate the color or other characteristics of the gold. For example, 18K gold can be white, yellow, or rose gold, depending on the other metals that are alloyed with it.
The karat scale is a valuable tool for understanding the purity of gold. It is used by jewelers, banks, and other institutions to ensure that customers are getting what they pay for.
