Gold Karats, Purity and Hallmarks Explained

Purity decides what you pay and what your gold is worth when you sell it. These guides explain karats in plain language, from 24K (99.9%) for bars and coins to 22K (91.6%, stamped 916) for most Indian jewellery, 21K for Arabic designs, 18K for diamond pieces and 14K for everyday wear.

You’ll also learn to read hallmarks. That covers Dubai’s purity stamps, India’s BIS hallmark with its 6-digit HUID, and how to verify a HUID in the BIS CARE app. Further guides cover which home purity tests actually work, how karatmeter (XRF) testing works, and what Indian jewellers do when you bring Dubai gold to sell or exchange.

Karats, Purity & Hallmarks – FAQs

What is the difference between 24K and 22K gold?
24K gold is 99.9% pure and mostly sold as bars and coins. 22K is 91.6% pure, harder and better for jewellery, which is why most Indian jewellery is 22K.
What does 916 mean on gold?
916 means the gold is 91.6% pure, which is 22 karat. It is the standard purity mark for Indian jewellery.
Can I sell Dubai gold in India?
Yes. Indian jewellers test the purity and value it by gold content. Dubai jewellery won’t carry an Indian HUID, so keep your invoice to show purity and weight.
