A. Chuan Journal — Sterling Silver, Explained
925 stamped inside a ring or on a clasp means the piece is sterling silver: 92.5% pure silver alloyed with 7.5% of another metal, almost always copper. Pure silver on its own is too soft to hold its shape through daily wear, so that small percentage of alloy is what lets a ring keep its edges and a chain resist bending out of true.
It's the same standard used by jewelers everywhere, which is why the number reads the same whether it's stamped in Italy, Thailand, or anywhere else. Here's what it tells you about the metal, the stamp itself, and what a piece is actually worth.

The basics
The number, explained
Fine silver — as close to pure as jewelry metal gets — is marked 999. It's also soft enough to dent with a fingernail, which makes it a poor choice for anything worn daily. Sterling silver solves that by mixing in 7.5% of a harder metal, almost always copper, giving the alloy enough structure to hold a clasp shut or keep a ring band round through years of wear.
925 is simply that ratio written as a number: 92.5 parts silver to 7.5 parts alloy, out of 100. It's an international standard, not a brand or a grade tied to one country, so a 925 stamp means the same thing regardless of where the piece was made.
The stamp itself
Reading the stamp
A genuine 925 stamp is small, crisp, and evenly spaced — usually tucked inside a ring band, on a clasp, or on the back of a pendant. Blurry lettering, uneven spacing, or a mark that looks oddly large for the piece are common signs something is off, though weighing the piece or asking a jeweler to test it is the more reliable check.
One detail that trips people up: a 925 stamp on a piece with a gold-tone finish doesn't mean the metal is gold. It means the base metal is sterling silver that's been plated in a gold-tone finish — the stamp describes what's underneath the surface, not the color on top.

Why the alloy matters
What that 7.5% is actually doing
The copper in sterling silver isn't a filler — it's what gives the metal enough hardness to be shaped into fine detail, like the butterfly outline on a pair of drop earrings, and to hold that shape through normal wear.
The tradeoff is that copper reacts with air and skin oils over time, which is why sterling silver naturally tarnishes — a normal part of owning it, not a flaw in the piece. We've written a longer guide on whether sterling silver tarnishes and how to slow it down if that's the part you're weighing before buying.

925 across a jewelry box
The same standard, applied differently depending on what's set alongside it.
With a statement stone
Sterling silver sets a natural stone like rutilated quartz without competing with it — the metal's job here is structure, not sparkle.
Shop the piece
With mixed natural materials
Resin, pearl, and mother of pearl all sit differently against silver than against gold — cooler, quieter, closer to how each material looks in its raw state.
Shop the piece
On a ring, specifically
Rings take more daily contact than almost anything else in a jewelry box — exactly where the alloy's hardness matters most.

What 925 means for value
Sterling silver carries two kinds of value. One is melt value — what the silver content is worth as raw metal, which moves with the silver market day to day. The other is resale value, which depends on design, craftsmanship, and condition, and is usually the larger factor for a piece meant to be worn rather than sold on.
That's also why 925 is worth buying for what it is — a durable, genuinely silver piece meant for daily wear — rather than as an investment. Pieces in our gifts under $100 collection are priced around the design and craftsmanship, not a resale premise, which is a more honest way to shop sterling silver day to day.
FAQ
Common questions
Is 925 real silver?
Yes. The 925 stamp means the piece is 92.5% pure silver, alloyed with a small percentage of another metal — almost always copper — for strength. It's genuine silver, not a coating or an imitation.
What does 925 mean on gold-colored jewelry?
It means the base metal is sterling silver that's been plated in a gold-tone finish. The 925 stamp describes what's underneath the plating, not the color you see on the surface.
Is 925 sterling silver worth anything?
Yes, in two ways: melt value tied to the current silver price, and resale value based on design, craftsmanship, and condition. For jewelry bought to wear rather than resell, the craftsmanship is usually worth more than the metal alone.
How can I tell if a 925 stamp is real?
Genuine stamps are small, crisp, and evenly spaced. Blurry or oddly sized lettering is a common sign of a fake, though weighing the piece or asking a jeweler to test it is the more reliable check.
925 is a straightforward promise: real silver, alloyed to be strong enough for daily wear. Start with one piece from our sterling silver jewelry collection, and let the stamp do the reassuring.
