Live 21ct Gold Price Per Gram
Wednesday, 21 October 2026, 13:15.
The LBMA (London Bullion Market Association) spot price changes daily.
The prices displayed are based on the global market rate for pure 24ct gold, known as the gold spot price. Like all gold dealers, GoldSell pays a percentage of this rate to account for assaying, refining, secure logistics, market volatility, and handling costs. We consistently offer among the highest payout rates in the UK, with the exact percentage increasing based on the weight and purity of the gold you sell.
Selling 21ct Gold?
Here’s what you need to know — and how we help thousands sell 21ct gold for the best price.
87.5% Pure Gold
21ct gold contains 87.5% pure gold, blended with a small percentage of durable metals like copper or silver to enhance its strength and tone. It’s a popular choice for high-purity gold jewellery—commonly used in rings, chains, pendants, and other valuable pieces.
How We Value Your 21ct Gold
Our valuations are based on the live gold price. Like other gold buyers and local jewellers, we factor in our costs to cover assaying (XRF testing), refining, insured postage and market risk, but we consistently offer the highest 21ct gold prices.
Live Price Checker™
Our Live Price Checker™ automatically scans competitor scrap gold prices across the UK twice daily. This ensures our payouts remain the most competitive, reinforcing our position as the UK’s highest-paying gold buyer.
Sell 21ct Gold Without A Hallmark
No hallmark? No problem. Every item is XRF scanned to determine true purity. Our valuations are based on actual gold content, not just gold hallmarks or stamps.
