Carat vs Karat: What Does Gold Purity Mean?

Gold is one of India`s most popular investments and a traditional choice for jewellery purchases. However, terms such as carat and karat often confuse buyers. Understanding these terms helps consumers make informed decisions when purchasing gold jewellery, coins or other gold products.

What Does Karat Mean in Gold?

Karat, commonly written as K, measures the purity of gold on a scale of 24. Pure gold is designated as 24K, while lower karat values indicate that gold is mixed with other metals.

For example, 22K gold contains approximately 91.6% gold, while 18K gold contains 75% gold. The remaining percentage consists of other metals that improve strength, durability or colour.

What Is the Difference Between Carat and Karat?

Although the words sound similar, they have different meanings in jewellery terminology.

Karat (K) measures gold purity. It helps buyers understand the proportion of gold present in an item.

Carat (ct) measures the weight of gemstones, including diamonds. One carat equals 200 milligrams.

Therefore, a 22K gold necklace describes the purity of its gold, while a one-carat diamond describes the weight of the diamond.

Why Does Gold Purity Matter?

Gold purity influences the metal`s value, colour, durability and suitability for different jewellery designs. Higher-purity gold contains more gold by weight but is generally softer than gold alloys.

Before buying jewellery, consumers should check the purity marking, BIS hallmark and HUID, where applicable.

Conclusion

Understanding carat and karat terminology helps Chennai gold buyers compare products accurately and avoid confusion. Always check the gold purity, weight and final invoice before completing a purchase.
