International Gold Markings Chart
The international gold markings chart is a system used to indicate the purity of gold in jewelry and other objects. It is a legal requirement in many countries, and it helps protect consumers from fraud.
The chart is based on the karat system, which measures the proportion of pure gold in an alloy. Pure gold is 24 karats, and each karat represents 1/24th of the total weight. For example, 18 karat gold is 18/24ths pure gold, or 75%.
In addition to the karat stamp, the chart also includes other markings that indicate the country of origin, the manufacturer, and the year of manufacture.
The following is a table of the most common international gold markings:
| Mark | Karat | Purity | Country of Origin |
|—|—|—|—|
| 24K | 24 | 100% | International |
| 22K | 22 | 91.7% | International |
| 18K | 18 | 75% | International |
| 14K | 14 | 58.3% | International |
| 10K | 10 | 41.7% | USA, Canada |
| 9K | 9 | 37.5% | UK, Ireland |
| 8K | 8 | 33.3% | Japan |
It is important to note that the international gold markings chart is not the only system used to indicate the purity of gold. Other systems, such as the millesimal fineness system, are also used in some countries.
When purchasing gold jewelry or other objects, it is important to be aware of the different gold markings systems and to understand what they mean. This information will help you to make informed decisions about the quality and value of your purchases.
