Platinum Melt Value Calculator
Platinum jewelry is usually 95% pure — marked PLAT, PT950, or 950 — far purer than most gold alloys. Enter a weight below to price it at the live platinum spot rate.
A quirk of the current market: platinum trades below gold per ounce, so a platinum ring is often worth less as metal than the same ring in 18K gold — surprising to sellers who remember when platinum was the premium metal.
| Purity | Fineness | Value per gram | Value per troy oz |
|---|---|---|---|
| .999 fine | 0.999 | $60.61 | $1,885.11 |
| PLAT 950 (.950) | 0.95 | $57.63 | $1,792.65 |
| .900 | 0.9 | $54.60 | $1,698.30 |
| .850 | 0.85 | $51.57 | $1,603.95 |

Marks and lookalikes
PT950/PLAT: 95% platinum. PT900: 90%. 'Platinum-plated', 'platinaire', and unmarked white metal are usually silver or base alloys. White gold is not platinum — it's gold alloyed pale and rhodium-plated, marked with karat stamps (14K, 18K, 750). Buyers separate the two instantly by density and XRF.
