International Gold Karat Rating
Gold karat rating is a measure of the purity of gold, indicating the percentage of gold in an alloy. The higher the karat, the purer the gold. The international gold karat rating system is used worldwide and is based on a 24 karat scale.
* 24 karat (99.9% pure): This is the purest form of gold and is often used in investment bullion coins and bars. It is too soft for most jewelry applications.
* 22 karat (91.6% pure): This high-karat gold is commonly used in fine jewelry, such as wedding bands and engagement rings. It offers a good balance of purity and durability.
* 18 karat (75% pure): This is a common karat for everyday jewelry, as it is harder and more durable than higher-karat gold while still maintaining a high gold content.
* 14 karat (58.3% pure): This is a popular choice for jewelry due to its affordability and durability. It is harder than higher-karat gold, making it more suitable for everyday wear.
* 10 karat (41.7% pure): This is the lowest karat gold used in jewelry. It is relatively affordable and durable but has a lower gold content than higher-karat gold.
The karat rating is often marked on jewelry with the abbreviation “K” or “Kt,” followed by the karat number. For example, “18K” or “18Kt” indicates 18 karat gold.
It’s important to note that gold alloys may contain other metals, such as copper, silver, zinc, or palladium. These alloys are added to increase the durability, color, or malleability of the gold.
The international gold karat rating system provides a standardized way to measure and compare the purity of gold in jewelry and other applications. Understanding the different karats and their properties can help consumers make informed decisions when purchasing gold items.
