Sterling Silver vs Silver Plated: How to Tell the Difference and Why It Matters

A lot of jewelry looks the same in a photo. The difference shows up later — in how it wears, how it feels, and whether it still looks good after a few years.

Sterling silver is an alloy that is at least 92.5% pure silver. The rest is usually copper, which gives the metal strength. Good makers often run slightly higher than the minimum. Plated jewelry is a thin layer of silver (or silver-colored metal) over a cheaper base. Once that layer wears through, the piece changes color and can irritate skin.

How to Spot Real Sterling

Look for a stamp: .925, 925, Sterling, or Ster. The stamp isn’t a guarantee of quality by itself, but its absence is a warning. Weight is another clue. Solid sterling feels denser than a plated piece of the same size. The details on a well-made knot or filigree stay sharp instead of looking soft or blurred.

Why the Difference Matters for Daily Wear

Plated pieces can look fine at first. With regular wear the plating thins, especially on rings and bracelet edges. Tarnish behaves differently too. Solid sterling tarnishes in a way that can be polished back. Once plating is gone, polishing only reveals the base metal underneath.

Price and Value

Solid sterling costs more up front because the metal itself has value and the labor to work it is higher. Over time many people find the extra cost is lower than replacing plated pieces every couple of years. For anything you plan to wear often or pass on, solid metal usually makes more sense.

What Peter Stone Does

Every piece is made from solid .925 or higher sterling silver (or actual karat gold). Nothing is plated. The metal is mixed and worked in the atelier so the quality stays consistent. That approach has been the same for decades because the difference is obvious once you handle the finished jewelry.
