Platinum is prized in jewelry for its natural white colour, density and durability, especially for engagement rings and wedding bands. Jewelry is also a significant source of platinum demand, historically led by Japan and China. But a piece of platinum jewelry is not the same as an investment bar, and understanding how it is valued can save you from unrealistic expectations.
Purity and Hallmarks
Platinum jewelry is marked in parts per thousand:
- Pt950 / PLAT / 950 Pt: 95% platinum, the most common standard in the US and Europe.
- Pt900: 90% platinum, widely used in Japan.
- Pt850: 85% platinum, used in some markets.
The rest is usually another platinum group metal such as ruthenium or iridium, or cobalt. Platinum is not measured in karats.
Why People Choose Platinum
- Naturally white: it doesn’t need rhodium plating, unlike white gold.
- Hypoallergenic for most people because of its high purity.
- Durable: when scratched, platinum is displaced rather than lost, and it develops a soft satin “patina” over time that can be re-polished.
- Heavy: about 21.4 g/cm³, so platinum pieces feel more substantial than gold ones of the same size.
Calculating Melt Value
The intrinsic (melt) value is the value of the platinum it contains:
Melt value = weight in grams × purity × (spot price per troy ounce ÷ 31.1035)
Use our platinum price per gram calculator with the current price from the live chart to do the arithmetic. Remove or deduct the weight of any gemstones first.
Retail Price vs Resale Value
Retail jewelry prices include design, labour, brand, gemstones and retailer margin, so they are usually well above melt value. When selling, a refiner or scrap buyer typically pays a percentage of melt value to cover refining costs and profit. Antique, signed or designer pieces can sell above melt value on the secondhand market, but most everyday jewelry resells at or below it.
Platinum vs Gold Jewelry
A Pt950 ring contains much more precious metal by weight than an 18k (75%) gold ring of the same design because platinum is both purer and denser. Whether the platinum ring is worth more in metal terms depends on the current gold and platinum prices — compare them on our gold vs platinum chart. Platinum can also cost more to work with, which raises labour charges.
Jewelry as an Investment?
Because of retail markups and resale discounts, jewelry is generally an inefficient way to gain exposure to the platinum price. People who want price exposure tend to look at bars, coins or exchange-traded products instead, each with its own costs and risks. Jewelry is best bought for wearing and enjoyment.
Frequently Asked Questions
How much is my platinum ring worth?
Its metal value is weight in grams times purity (0.95 for Pt950) times the spot price per gram. A buyer will usually pay less than this; design, brand and gemstones can add value on the secondhand market.
Does platinum jewelry hold its value?
The platinum content tracks the platinum price, which can be volatile. Retail markups mean resale prices are usually well below what was paid in a shop.
