Diamonds are timeless symbols of beauty and luxury, but with so many imitations on the market, it’s important to know how to spot the real deal. Whether you’re buying a diamond or verifying one you own, here’s a quick guide to help you distinguish real diamonds from fakes.
What Makes a Diamond Real?
Natural diamonds are genuine gemstones composed of carbon, created through intense pressure and heat. They are recognized by their brilliance, hardness (10 on the Mohs scale), and distinct refraction of light. Lab diamonds, as chemically equivalent, are grown in a laboratory setting and tend to be cheaper.
Common Fake Diamonds
- Cubic Zirconia (CZ): Shiny but softer and less brilliant.
- Moissanite: Similar sparkle but different optical properties.
- Glass or Crystal: Low-cost and less durable.
- Synthetic Diamonds: Lab-created but not natural.
How to Spot a Real Diamond
- The Fog Test: Breathe on the diamond. A real diamond will clear instantly, while a fake will stay foggy.
- The Water Test: Drop the diamond in water. Real diamonds sink many fakes float.
- The Dot Test: Place the diamond on a dot. If you see the dot through the stone, it’s likely fake.
- Sparkle and Inclusions: Real diamonds have unique brilliance and often tiny flaws (inclusions).
Professional Verification
- Use a loupe to check for inclusions.
- Invest in a diamond tester to measure thermal conductivity.
- Always ask for certification from reputable labs like GIA or AGS.
Red Flags
- Prices that seem too good to be true.
- Lack of certification or documentation.
- Poor craftsmanship in the setting.
Lab-Grown Diamonds: Real or Fake?
Lab-grown diamonds are real but not natural. They’re a great budget-friendly option with the same physical properties as mined diamonds.
Tips for Buying Diamonds
- Buy from reputable jewellers.
- Ask for certification.
- Educate yourself on the 4 Cs (Cut, Clarity, colour, Carat Weight).
Conclusion
Identifying real diamonds is easier with the right knowledge and tools. Use simple tests like the fog or water test, and always verify with a professional if in doubt. Whether natural or lab-grown, a real diamond is a timeless investment.
