22k vs 24k gold: what is the real difference?

The simple answer is purity. 24k gold is 99.9% pure gold. 22k gold contains 91.6% gold — the remaining 8.4% is usually copper, silver, or zinc. The useful part is what that means in real buying. 24k is the standard for bullion bars, coins, and live price benchmarks. 22k dominates jewellery markets in India, the UAE, and the Gulf because the alloy makes the gold harder and more suitable for detailed work.

How 22k and 24k compare on the numbers that matter for buying

A practical example: if the spot price is USD 95 per gram, a 22k item weighing 10 grams has a pure-gold value of approximately USD 870 (10 × 95 × 0.916). A 24k item of the same weight has a value of approximately USD 950 (10 × 95 × 0.999). The 22k item costs less because there is less gold content per gram — not because gold itself is cheaper.

In India and the Gulf, the real question is usually live rate versus showroom price

Most people asking about 22k versus 24k are not comparing chemistry. They are comparing the rate they see on a gold price website with the quote a jeweller is giving them in a shop. The gap between the two is usually explained by three things: purity (22k versus 24k), making charges (typically 8–20% of the gold value for jewellery), and the dealer's retail margin.

This is why two people can both say they bought gold at the market price and end up paying very different amounts. One bought a 24k bullion bar at a small premium over spot. The other bought 22k jewellery with making charges on top. Both are legitimate — they represent different products with different cost structures.

Use 24k as the benchmark, then switch to 22k when comparing jewellery quotes

The live gold price shown on this site and most market data sources is a 24k benchmark in USD per gram or troy ounce. This is the anchor for any gold decision. Once you know the 24k benchmark, calculate the 22k metal value by multiplying by 0.916. If a jewellery quote is significantly above that 22k metal value, the difference is making charges and dealer margin.

• For investment buying: use the 24k benchmark and look for bars or coins with low premiums over spot.
• For jewellery buying: start with the 22k metal value, then ask the seller to show making charges separately.
• For scrap gold: identify the karat mark, calculate pure-gold content, and compare payout to the benchmark.

18k, 14k, and 10k — the same framework applies

18k gold is 75% pure, common in European jewellery. 14k is 58.5% pure, common in the US. 10k is 41.7% pure and used in lower-cost formats. The formula is the same in each case: spot price × weight × purity fraction. Making charges and dealer margin still apply on top of that metal value for retail jewellery at any karat.

How to identify purity: hallmarks and what they mean

Most gold items carry a small hallmark stamp that indicates purity. In India, the Bureau of Indian Standards (BIS) hallmarks are the official standard. BIS 916 means 22k (91.6% pure), while BIS 999 means 24k (99.9% pure). In Europe, the Assay Office hallmarks follow the same logic: 916 is 22k, 750 is 18k, 585 is 14k. The hallmark system protects buyers by offering third-party certification of purity. When buying jewellery or bars, always look for a recognized hallmark from a trusted assay office.

• BIS 916 (India) = 22k, legally certified in India.
• BIS 999 (India) = 24k, used for investment bars and high-purity jewellery.
• British Assay Office hallmarks (UK) = official stamps indicating purity and year of assay.
• European hallmarks follow the same fraction system: 999, 916, 750, 585, 417.
• Unmarked or poorly marked gold is a red flag — purity cannot be verified.

Why 22k and 24k pricing differences go beyond purity alone

At April 2026 rates with spot gold around USD 3,200 per troy ounce (approximately USD 102.88 per gram), the pure-metal value difference is significant. Pure 24k gold is worth USD 102.88 per gram at spot. The same weight of 22k gold contains only 91.6% of that pure gold, making it worth approximately USD 94.31 per gram at spot. But in retail markets, the 22k price often sits much closer to the 24k price because jewellery premiums, making charges, and dealer margins apply to both equally. This is why two jewellers can quote very different prices for the same purity — the difference reflects their making charge and margin structure, not the gold purity alone.
