International Gold Karat
Karat (Kt) is a unit of measurement used to express the purity of gold. It represents the parts of gold per 24 parts of the alloy. Pure gold is 24 karats, which means that it contains 24 parts of gold and no other metals.
The international gold karat system is a standardized method of measuring gold purity that is used in many countries around the world. This system is based on the parts per thousand of gold in the alloy, with 24 karat being pure gold and lower karats indicating a lower gold content.
The following table shows the international gold karat system and its corresponding gold content:
| Karat | Gold Content (%) | Description |
|—|—|—|
| 24 | 100 | Pure gold |
| 22 | 91.7 | High karat gold, often used in jewelry |
| 18 | 75 | Common karat for jewelry, known as “18K” |
| 14 | 58.3 | Durable karat for everyday wear |
| 12 | 50 | Lower karat gold, often used in decorative items |
| 10 | 41.7 | Common karat for gold-filled jewelry |
| 9 | 37.5 | Lower karat gold, often used in industrial applications |
The international gold karat system is important for consumers because it allows them to understand the purity and value of gold jewelry. Higher karat gold is more valuable and durable, while lower karat gold is less expensive and may be more suitable for certain types of jewelry.
When purchasing gold jewelry, it is important to look for the karat stamp, which indicates the purity of the gold. This stamp will typically be located on the inside of the jewelry piece and will indicate the karat number, such as “18K” or “14K”.
