How to Identify Silver

Hallmark Test

Look for a stamp on the item using a magnifying glass or loupe. Check the locations listed in our 925 guide.

1. Get a magnifying glass or jeweler's loupe (10x magnification)
2. Check inside rings, on clasps, back of handles, bottom of items
3. Look for numbers (925, 800, 999) or words (STERLING, STER)
4. Cross-reference with the hallmark grid above

Magnet Test

Silver is not magnetic. A neodymium magnet provides the most reliable results.

1. Get a strong neodymium magnet (rare earth magnet)
2. Hold the magnet near the silver item
3. Real silver: No attraction (may slide slowly on angled silver)
4. Fake: Strong attraction = ferrous metal with silver coating

Note: Passing the magnet test alone doesn't confirm silver — other non-magnetic metals exist. Combine with other tests.

Ice Test

Silver has the highest thermal conductivity of any metal. Ice melts almost instantly on real silver.

1. Place the silver item on a flat surface
2. Put an ice cube on top of the item
3. Real silver: Ice starts melting immediately, much faster than on a regular surface
4. Fake: Ice melts at a normal rate

Ring Test

Real silver produces a distinctive musical ring when struck gently.

1. Balance the item on your fingertip (coins work best)
2. Tap gently with another coin or metallic object
3. Real silver: Clear, high-pitched, sustained ring lasting 1-2 seconds
4. Fake: Dull, short thud

Acid Test / Professional Assay

The definitive test. A drop of nitric acid on the surface reveals the metal composition by color.

1. Option A: Buy a silver testing acid kit (~$15-25)
2. Make a small scratch on an inconspicuous area
3. Apply a drop of nitric acid to the scratch
4. Real silver: Creamy white reaction → Fine silver; Light grey → Sterling
5. Option B: Take to a jeweler for XRF analysis (non-destructive, most accurate)
