Platinum is one of the rarest precious metals — about 30 times rarer than gold. Calculating its value follows the same principle as gold and silver: weight × purity × spot price per gram.
Unlike gold, which comes in many carats, platinum jewellery in the UK is almost exclusively 950 purity (95% platinum, 5% alloy — usually ruthenium or cobalt for hardness).
| Hallmark | Name | Platinum Content | Common Uses |
|---|---|---|---|
| 999 | Fine Platinum | 99.9% | Bullion bars & coins |
| 950 | Standard Platinum | 95.0% | UK jewellery, engagement rings |
| 900 | 900 Platinum | 90.0% | Some vintage & European pieces |
| 850 | 850 Platinum | 85.0% | Older jewellery, dental |
In the UK, any item described as “platinum” must be at least 850 parts per thousand (85%) and must carry an assay office hallmark if it weighs 0.5 grams or more.
A typical platinum engagement or wedding ring weighs between 4 and 10 grams. Here are some worked examples at today's prices:
| Ring Type | Weight | Spot Value | Dealer Offer (est.) |
|---|---|---|---|
| Slim band | 4 g (950) | £155.84 | ~£112.20 |
| Standard ring | 6 g (950) | £233.76 | ~£168.31 |
| Heavy band | 8 g (950) | £311.68 | ~£224.41 |
| Wide wedding ring | 10 g (950) | £389.60 | ~£280.51 |
Dealer offers for platinum jewellery typically range from 70–75% of spot value. Coins and bars attract higher offers (80–90%). Get multiple quotes from our dealer directory to maximise your return.
Yes — automotive catalytic converters contain platinum group metals (PGMs) including platinum, palladium, and rhodium. A typical catalytic converter contains 3–7 grams of PGMs.
Important legal note: Under the Scrap Metal Dealers Act 2013, it is illegal in England and Wales to buy or sell catalytic converters removed from vehicles unless you hold a scrap metal dealer's licence. Catalytic converter theft carries severe penalties. Only sell through licensed motor salvage operators or vehicle dismantlers.
If you have a legitimately obtained catalytic converter (e.g. from your own end-of-life vehicle), a licensed scrap dealer can test and value the PGM content.
It depends on current prices. Historically, platinum was more expensive than gold, but since 2014 gold has generally traded at a premium. Today, fine platinum is £41.01/g. Check our platinum price per gram page for a live comparison with gold.
No. When you sell platinum to a UK dealer, you receive the agreed price with no VAT deduction. VAT (20%) applies only when purchasing platinum bullion, making the buy/sell spread wider than for gold.
Check the hallmark. Platinum is stamped with an orb and cross symbol alongside the purity number (e.g. 950). White gold is stamped with a crown (for gold) and a carat number like 750 (18ct). Platinum is also noticeably heavier than white gold of the same size.
Yes. Dental crowns and bridges sometimes contain platinum alloys. A dealer can test the metal content with XRF analysis. Dental platinum is typically 850–900 purity and is valued at the corresponding scrap rate.
