How to Check Silver Purity at Home: A Complete Guide for Silver Jewellery Buyers

Introduction

Silver jewellery is timeless — it's elegant, affordable, and perfect for everyday wear. But with rising demand, the market is also flooded with fake or low-quality silver. If you're someone who loves wearing or gifting silver jewellery, knowing how to check silver purity at home is essential.

In this complete guide, we’ll show you how to test silver purity easily and what makes 92.5 sterling silver jewellery the best choice for daily wear.

Why Silver Purity Matters

• Skin safety: Low-purity or fake silver can cause rashes or allergies.
• Tarnish resistance: Genuine 925 silver is less likely to tarnish with proper care.
• Value for money: Pure silver retains its shine and worth longer.
• Authenticity: Avoid being cheated by sellers who offer silver-plated items as real.

7 Effective Ways to Test Silver Purity at Home

1. Check for Hallmark or Stamp (925 mark)

Always look for the “925” hallmark. This means 92.5% pure silver – also called sterling silver.

Where to find it?

• On the inner side of rings or bangles
• On the clasp of necklaces
• On the back of earrings

If there’s no stamp, chances are it's either silver-plated or impure.

2. Magnet Test

Real silver is not magnetic. Bring a strong magnet close to your silver jewellery.

• If it sticks: it’s fake.
• If it doesn’t: it might be real, but further tests are needed.

3. Rub Test

Rub the jewellery gently with a white cloth. If:

• Black marks appear → It's a good sign (oxidation, a property of real silver).
• No marks or greenish tint → Possibly fake or silver-plated.

4. Ice Cube Test

Silver has the highest thermal conductivity among all metals.

• Place an ice cube on your silver piece.
• If it melts quickly → it's likely real.
• If not → it's probably fake or alloyed.

5. Sound or "Ping" Test

Gently tap your silver piece with a metal item.

• Real silver makes a long, high-pitched ringing sound.
• Fake silver or alloys sound dull and short.

6. Acid Test (Nitric Acid)

Caution: Perform only if you're comfortable using chemicals.

• Apply a drop of nitric acid on a small hidden area.
• If it turns green, it's fake.
• If it turns creamy white, it's genuine sterling silver

7. Professional Lab or Jeweller Test

When in doubt, visit a BIS-certified jeweller and get your jewellery tested using:

• XRF machines
• Touchstone method
• Spectrometry tests
