Diamonds have always symbolized love, luxury, and timeless elegance. Whether you’re buying an engagement ring, upgrading your jewelry collection, or simply curious about the stone in your possession, knowing how to tell if a diamond is real is crucial. With the growing popularity of lab-grown diamonds and moissanite, as well as the presence of imitations like cubic zirconia, consumers must be equipped with the right knowledge.

That’s why Solomon Jeweler, a trusted name in fine jewelry, ensures complete transparency and certification for every piece they offer, whether natural, lab-grown, or moissanite.

Why Identifying Real Diamonds Matters

  • Financial Value: Diamonds are a major investment, so ensuring authenticity protects your money.
  • Emotional Value: Engagement rings and milestone jewelry pieces carry deep sentimental meaning.
  • Resale & Insurance: Only genuine certified diamonds hold long-term value and can be insured properly.

Common Types of Diamonds in the Market

  1. Natural Diamonds – Formed over billions of years in the Earth’s mantle.
  2. Lab-Grown Diamonds – Chemically identical to natural diamonds, created using advanced technology.
  3. Moissanite – A diamond alternative with stunning brilliance and durability.
  4. Diamond Simulants – Includes cubic zirconia (CZ), white sapphire, and glass imitations.

Physical Tests to Identify a Real Diamond

Here are a few quick at-home tests you can try:

The Fog Test

Breathe on the diamond. If the fog disappears instantly, it’s likely real. Fake stones retain moisture longer.

Water Test

Drop the stone in a glass of water. Real diamonds sink due to their density, while fakes may float or sink slowly.

Scratch Test (Use Caution)

Diamonds are the hardest natural substance. While they can scratch glass, this method is not recommended, as it may damage your jewelry.

UV Light Test

Under UV light, many diamonds emit a blue fluorescence. However, absence of fluorescence doesn’t mean it’s fake.

Professional Methods to Authenticate Diamonds

For absolute certainty, professional jewelers use scientific methods:

  • Loupe Examination – Checking for natural inclusions and imperfections.
  • Thermal Conductivity Test – Real diamonds disperse heat rapidly, unlike most fakes.
  • Electrical Conductivity Test – Helps distinguish moissanite from diamonds.
  • Certification – Always ask for GIA, IGI, or AGS certification when buying.

Lab-Grown vs Natural Diamonds: Can You Tell the Difference?

Lab-grown diamonds look identical to natural diamonds to the naked eye. Only specialized equipment can differentiate them.

  • Visual: Both sparkle brilliantly.
  • Durability: Both rank 10 on Mohs hardness scale.
  • Value: Natural diamonds often carry higher resale value, while lab-grown diamonds are more affordable.

Moissanite vs Diamond: Key Differences

Moissanite is a popular diamond alternative offered by Solomon Jeweler:

  • Brilliance: Moissanite sparkles with rainbow-colored flashes, while diamonds reflect white light.
  • Hardness: Nearly as hard as diamonds, ranking 9.25 on Mohs scale.
  • Price: A fraction of the cost of diamonds, making them budget-friendly.

Signs of Fake Diamonds & Common Simulants

  • Cubic Zirconia (CZ) – Softer and less brilliant than diamonds.
  • White Sapphire – Lacks the sparkle and hardness of diamonds.
  • Glass & Crystal Imitations – Easily scratched and less durable.
