Carat vs Karat: Understanding the Difference in Jewellery

In the jewellery industry, accuracy and knowledge are just as valuable as craftsmanship.
One of the most commonly misunderstood terms among buyers and even new professionals is the difference between Carat and Karat.

Although these words sound similar, they represent two completely different measurements. Understanding this distinction is essential for correct pricing, valuation, and trust—especially in gold and diamond jewellery.

What Is Karat (K)? – Gold Purity Explained

Karat (K) is a unit used to measure the purity of gold in jewellery.

Pure gold is very soft, so it is often mixed with other metals for strength and durability. Karat indicates how much pure gold is present in that mixture.

Common Gold Karat Standards:

• 24K Gold – 99.9% pure gold

• 18K Gold – 75% pure gold (ideal for fine jewellery)

• 14K Gold – 58.5% pure gold (strong and durable for daily wear)

For jewellery manufacturers and retailers, gold karat directly affects:

• Product pricing

• Manufacturing decisions

• Customer trust and certification

What Is Carat (ct)? – Gemstone Weight Explained

Carat (ct) is a unit used to measure the weight of gemstones, especially diamonds.

• 1 Carat = 0.2 grams

Carat weight plays a major role in determining the value of diamonds and other precious stones. However, it is important to understand that carat does not measure size alone. Cut, shape, and proportions also influence how large a gemstone appears.

Why the Difference Between Carat and Karat Matters

Confusing carat with karat can lead to:

• Incorrect pricing and valuation

• Errors in B2B transactions

• Issues in export documentation and compliance

• Loss of buyer confidence

In international jewellery trade and B2B manufacturing, even small misunderstandings can result in costly mistakes.
