Why Gold Purity Matters

Gold isn’t just a precious metal—it’s an investment, a cultural symbol, and a timeless accessory. However, counterfeit or low-purity gold can tarnish quickly, lose value, or even cause skin irritation. In Dubai, where gold shopping is a cultural staple, ensuring authenticity is crucial. At Sana Jewellers, we’ve simplified the process of verifying gold purity, empowering you to shop confidently.

5 Simple DIY Tests to Check Gold Purity

1. The Magnet Test

How It Works: Pure gold is non-magnetic

1. Hold a strong magnet close to your jewelry.

2. If it sticks, the piece contains iron, nickel, or other base metals.
   Note: This is a preliminary test—some fake gold alloys may still pass.

2. The Hallmark Check

What to Look For:

• 18K Gold: Stamped with “750” (75% purity).

• 21K Gold: Stamped with “875” (87.5% purity)

• 22K Gold: Stamped with “916” (91.6% purity).
  Tip: Use a magnifying glass to inspect engravings. Blurred or missing stamps are red flags.
  
  

3. The Ceramic Scratch Test

1. Gently rub the gold against unglazed ceramic.

2. Real gold leaves a golden streak; fake gold leaves a black/gray mark.

4. The Vinegar Test

1. Soak the jewelry in white vinegar for 15 minutes.

2. Real gold remains unaffected; fa

3. ke gold tarnishes or discolors.

5. The Density Test

Formula: Density = Mass ÷ Volume
Pure Gold Density: 19.3 g/cm³.
How to Calculate:

1. Weigh the gold.

2. Submerge it in water to measure displaced volume.

3. Use the formula to verify density.
