Understanding the Meaning of “International Gold 375”
“International Gold 375” is a term used to describe the purity of gold in a particular object. It refers to the percentage of pure gold in the alloy, with 375 indicating that the object is composed of 37.5% pure gold.
Karat System
The purity of gold is typically measured using the karat system. Pure gold is considered 24 karats (24K), while lower karats indicate a lower percentage of pure gold. 375K gold, therefore, contains 9 karats of pure gold:

375 / 1000 * 24 = 9 karats

Composition
375K gold is an alloy, meaning it is a mixture of pure gold and other metals. The most common metals used to alloy gold are copper and silver. In 375K gold, the remaining 62.5% of the alloy is typically composed of copper.
Durability
The addition of other metals to gold increases its strength and durability. Pure gold is a soft metal, so alloying it with other metals makes it more resistant to bending, scratching, and wear. 375K gold is a popular choice for jewelry because it is affordable, durable, and has a warm, golden color.
Identification
Objects made of 375K gold are often stamped with the “375” mark. Additionally, they may have other markings indicating the manufacturer or country of origin.
Uses
375K gold is commonly used in the production of jewelry, including rings, necklaces, bracelets, and earrings. It is also used in some watch cases, coins, and decorative objects.
Conclusion
“International Gold 375” is a term that describes the purity of gold in an object. It indicates that the object contains 9 karats of pure gold and is alloyed with other metals, typically copper. 375K gold is a popular choice for jewelry due to its affordability, durability, and golden appearance.
