Meaning of 750 International Gold
In the world of jewelry, the purity of gold is often indicated by a number followed by the letter “K” or “Kt.” The number represents the percentage of pure gold in the alloy, with 24K or 24Kt indicating 100% pure gold.
The term “750 international gold” refers to a gold alloy that contains 75% pure gold. This alloy is commonly used in jewelry because it is durable, retains its color well, and is less expensive than pure gold.
Composition of 750 International Gold
750 international gold is composed of:
* 75% pure gold
* 25% other metals, typically copper, silver, or zinc
The specific composition of the alloy can vary depending on the desired properties. For instance, adding more copper can increase the hardness and durability of the alloy, while adding more silver can result in a whiter color.
