Karat (kt or k) is a measurement of the purity of gold, with 24 karat (24k) being the purest form of gold. The higher the karat number, the purer the gold.
Here are the main differences in karat gold:
24 karat gold: This is the purest form of gold, with no other metals mixed in. It is also the softest and most malleable form of gold, making it not as durable as other forms of gold.
22 karat gold: This gold contains 22 parts pure gold and 2 parts other metals. It is slightly less pure than 24 karat gold, but still considered high-quality.
18 karat gold: This gold contains 18 parts pure gold and 6 parts other metals. It is more durable than higher karat golds and is often used in jewelry.
14 karat gold: This gold contains 14 parts pure gold and 10 parts other metals. It is more durable than 18 karat gold and is often used in everyday jewelry.
10 karat gold: This gold contains 10 parts pure gold and 14 parts other metals. It is less pure than higher karat golds, but is still considered real gold.
The most common karat gold in the jewelry market is 18K and 14K, due to their durability, while 22K and 24K are used in coins and some special ornaments.
The purity of gold affects the color of the metal, with higher karat golds being more yellow in color and lower karat golds being more white in color.
