Understanding Gold Karats: A Guide to Choosing the Right Gold for You
Gold jewelry and accessories often come in various karat options, each with its unique blend of purity, durability, and appearance. Understanding the differences between gold karats can help you make an informed choice when purchasing fine jewelry.
What is a Karat?
In gold, a karat (abbreviated as “k” or “kt”) measures its purity. Pure gold is 24 karats, meaning it is composed of 100% gold. Since pure gold is soft and malleable, it’s often mixed with other metals to increase durability, creating different karat levels.
Each karat represents 1/24th of the whole, meaning a 24-karat gold piece is 100% pure gold, while 18-karat gold is 18 parts gold and 6 parts other metals, or 75% pure gold.
