What Does 950 Mean on a Ring?
A 950 stamp on a ring almost always means it is made of 950 platinum — an alloy containing 95% pure platinum and 5% other metals, typically ruthenium, cobalt, or iridium. This is the most common platinum standard for jewelry.
The Full Explanation
The 950 mark on a ring indicates that the piece is made from an alloy containing 950 parts per thousand of pure platinum. This makes it 95% platinum by weight, with the remaining 5% consisting of other platinum-group metals or cobalt that improve the alloy's working properties. Platinum 950 is the dominant standard for platinum jewelry worldwide and is the minimum purity required for a piece to be simply labeled 'Platinum' in the United States under FTC regulations.
Platinum is one of the rarest and most precious metals used in jewelry — approximately 30 times rarer than gold. Its natural white color does not fade or change over time, unlike white gold, which requires periodic rhodium replating to maintain its appearance. Platinum is also hypoallergenic, making it an excellent choice for people with metal sensitivities. These properties, combined with its exceptional density and heft, make platinum the prestige choice for engagement rings and wedding bands.
One important characteristic of platinum is how it wears. Rather than losing metal when scratched (as gold does), platinum displaces — the metal moves rather than being removed. Over time, this creates a natural matte finish called a patina that many platinum enthusiasts prize. If you prefer the bright, polished look, a jeweler can re-polish your platinum ring to restore its original mirror finish at any time, and no metal is lost in the process. Platinum rings can literally last forever with proper care.
Where to Look
The 950 stamp is found on the inside of the ring band. It may appear as '950', 'Pt950', 'PLAT', 'PLAT950', or 'Pt' followed by '950'. Some rings also display the manufacturer's mark, a brand logo, or an additional quality stamp. On platinum, the stamp may be harder to read than on gold or silver because platinum's hardness can make stamping more challenging — use a jeweler's loupe for best results.

Frequently asked questions
Is 950 platinum better than 18K gold for an engagement ring?
Both are excellent choices with different advantages. Platinum is more durable long-term, hypoallergenic, and maintains its white color forever. 18K gold is available in yellow, white, and rose colors, is slightly easier to resize, and is currently less expensive per gram despite having a lower raw material cost. Platinum is the prestige choice; gold offers more color versatility.
Why is platinum more expensive than gold?
Platinum's higher cost stems from its extreme rarity (30 times rarer than gold), the difficulty of mining and refining it, and the higher purity used in jewelry (95% vs. 75% for 18K gold). Additionally, platinum is denser than gold, so a platinum ring uses more metal by weight than an identically sized gold ring. The combination of rarity, purity, and density all contribute to the price premium.
Will a 950 platinum ring scratch?
Yes, platinum scratches just like any metal. However, platinum scratches differently from gold — rather than losing material, platinum displaces, meaning the metal pushes aside rather than wearing away. This means your ring retains its weight and volume even after years of wear. Scratches develop into a soft patina that many people find attractive, and a jeweler can re-polish the ring to restore its original shine.
