The Complete Indian Gold Buying Guide
Essential knowledge on BIS hallmarking, purity karatage, making charges, and transparent pricing.
1. Understanding Karatage & Purity (24K vs 22K vs 18K)
The purity of gold is measured in karats out of 24 parts:
- 24 Karat (99.9% pure): Pure elemental gold. Soft and malleable; best suited for gold coins, bars, and bullion investment.
- 22 Karat (91.6% pure / 916): The quintessential Indian jewellery standard. Blended with copper/silver to give strength and retain glorious rich luster.
- 18 Karat (75.0% pure / 750): Ideal for setting natural diamonds and gemstones due to its superior prong grip.
