Understanding Gold Purity: 18K, 22K, and 24K Explained

Understanding gold purity is essential whether you're buying jewellery or investing. Let's decode the karat system.

What are Karats?

Karats (K) measure the purity of gold. Pure gold is 24 karats. The karat number tells you how many parts out of 24 are pure gold.

24K Gold (99.9% Pure)

The purest form of gold with a bright yellow color. Too soft for most jewellery, it's ideal for investment purposes — coins, bars, and digital gold. This is what powers Sri Sai Jewellers' digital gold platform.

22K Gold (91.6% Pure)

The most popular choice for Indian jewellery. With 22 parts gold and 2 parts alloy metals, it's more durable than 24K while retaining the warm gold color. BIS Hallmark standard for jewellery.

18K Gold (75% Pure)

With 18 parts gold and 6 parts alloy, this is highly durable and scratch-resistant. Available in yellow, white, and rose gold variants, it's popular for western-style jewellery and diamond settings.
