International Gold Karat Differences
Gold karat is a unit of measurement that indicates the purity of gold in an alloy. A pure gold is 24 karats, while an alloy with 10 karats of gold and 14 karats of other metals is 10 karat gold.
The karat system is used in most countries around the world, but there are some slight differences in the way that it is defined. In the United States, for example, a 10 karat gold alloy must contain at least 10 parts of gold per 24 parts of total weight. In the United Kingdom, however, a 10 karat gold alloy must contain at least 10 parts of gold per 22 parts of total weight.
This difference in definition can lead to confusion when buying gold jewelry from different countries. For example, if you buy a 10 karat gold ring from the United States and then try to sell it in the United Kingdom, you may get less money for it because it does not meet the UK’s definition of 10 karat gold.
It is important to be aware of the different karat definitions when buying or selling gold jewelry. If you are unsure about the karat of a piece of jewelry, you can always ask a jeweler to test it for you.
Here is a table that summarizes the different karat definitions in the United States, United Kingdom, and Europe:
| Country | Karat Definition |
|—|—|
| United States | 10 parts gold per 24 parts total weight |
| United Kingdom | 10 parts gold per 22 parts total weight |
| Europe | 10 parts gold per 24 parts total weight |
As you can see, the only difference in the karat definitions is in the United Kingdom, where 10 karat gold must contain 10 parts of gold per 22 parts of total weight.
