You've seen it stamped on the back of earrings and the inside of rings: 925. Or maybe your mom always asked, "Is it 92.5?" before buying silver. They mean the same thing, and it's the most important number in silver jewelry.
What does 925 or 92.5 silver mean?
925 silver, also called 92.5 silver or sterling silver, is 92.5% pure silver. The other 7.5% is usually copper, added to make the metal strong enough to wear every day.
Same metal, different ways of saying it:
- 925 is how it's usually stamped on jewelry.
- 92.5 is how many Indian families and jewelers say it.
- Sterling silver is the common name in the US and UK.
Is 92.5 silver "pure silver"?
When people shop for pure silver Indian jewellery, they usually mean real silver jewelry instead of plated brass or alloy. In that everyday sense, 92.5 silver is the real deal.
Technically, though, the purest silver is fine silver, or 999 silver, which is 99.9% silver. Here's how they compare:
- 999 fine silver: 99.9% silver. Very soft and bends and scratches easily, so it's mostly used for coins, bars, and some puja items.
- 92.5 sterling silver: 92.5% silver plus a little copper for strength. This is the standard for fine silver jewelry because it holds intricate details and survives daily wear.
Does 92.5 silver tarnish?
Yes, a little, and that's actually a sign it's real. The copper in sterling silver reacts with air and moisture over time, which can darken the surface. Fine silver tarnishes more slowly, but it's too soft for most jewelry. The good news: tarnish on sterling is easy to clean. Here's our guide to tarnished silver.
How do I know my jewelry is real 92.5 silver?
- Look for a 925, S925, or STER stamp on the back, clasp, or post.
- Buy from a brand that lists the metal clearly on every product page.

What about gold plated 92.5 silver?
Many Indian designs, especially temple jewelry, are 92.5 silver with gold plating on top. You get the warm gold look with a precious metal underneath, so when the plating softens over time, you still have real silver. Learn more in gold plated silver vs. gold plated brass.
