Karat vs purity — what's the difference?

'Karat' is a fraction of 24 — 24K is 100% gold (in practice 99.9%), 18K is 18/24ths (75%), and so on. 'Fineness' is the same thing expressed in parts-per-thousand: 999 = 24K, 916 = 22K, 750 = 18K, 585 = 14K, 417 = 10K. The number stamped on a hallmark always means the same thing.

Frequently asked questions

What does 24K gold mean?

24K (or 24-karat) is the purest form of gold, 99.9% pure. The remaining 0.1% is trace alloy. 24K is sold as investment bars and coins but is too soft for everyday jewellery — it dents and scratches easily.

Is 22K or 18K better for jewellery?

22K (91.7% pure) holds its value better and is the South Asian/Gulf jewellery standard — softer, deep yellow. 18K (75% pure) is the European and engagement-ring standard — harder, paler, sits flush on stones. Pick 22K for resale, 18K for daily wear with gemstones.

How do I calculate scrap gold value?

Weigh your item in grams. Multiply by today's spot price per gram, then by the purity factor (24K=1.0, 22K=0.917, 18K=0.750, 14K=0.583, 10K=0.417). Subtract dealer margin (5–25%). This calculator does the math live.

What about 21K Khaleeji gold?

21K (87.5% pure) is the Gulf — UAE, Saudi Arabia, Bahrain, Qatar — jewellery standard, traditional yellow hue, harder than 22K. Less common outside the Gulf so resale value drops 5–8% if you sell elsewhere.
