How to Check if a Gemstone is Real or Fake – A Complete Guide by OneStep Gems

Are you wondering how to check if a gemstone is real or fake? With so many synthetic and imitation gems flooding the market, it's more important than ever to understand gemstone authenticity, especially when making an investment in natural beauty.

At OneStep Gems, we believe in 100% natural, ethically sourced gemstones backed by transparency and lab certifications. In this complete guide, we’ll teach you how to identify real gemstones versus fake stones using both home methods and professional techniques.

 Why Knowing the Difference Matters

  • Protect Your Investment: Natural gemstones hold long-term value.
  • Spiritual & Healing Properties: Only original gems carry natural energy and metaphysical benefits.
  • Certification & Trust: You deserve full transparency on what you’re buying.

📌 Types of Gemstones: Know What You're Looking At

Understanding the types of gemstones is the first step:

Type Description
Natural Mined from the earth with minimal treatment. These are real, original gems.
Synthetic Lab-created, same composition as natural but not mined.
Imitation (Fake) Glass, resin, or plastic made to look like real gems.

At OneStep Gems, we only deal in natural, untreated, certified gemstones.

 How to Check If a Gemstone is Real at Home
 1. Visual Inspection for Inclusions

  • Real gemstones usually have small inclusions or natural flaws.

  • If the stone looks perfect, it could be synthetic or fake.

Use a 10x jeweler's loupe to examine:

  • Inclusions
  • Color zoning
  • Natural lines
  • Bubbles (indicate glass)

2. The Fog Test

  • Breathe on the gemstone.
  • Real gems clear up almost instantly.
  • Fakes, especially glass, stay foggy longer.

 3. Weight Test

Use a precision scale:

  • Natural stones have a higher density.
  • Fakes (glass/plastic) are lighter in comparison.

 4. Scratch Test (Be Cautious)

Gemstones like sapphire, ruby, and diamond are hard:

  • Try scratching the surface lightly with a material of lower hardness (e.g., a copper coin).
  • Real gemstones won't scratch easily. However, don’t use this on soft stones (e.g., opal, turquoise).

 Professional Methods to Verify Gemstone Authenticity

 5. Refractometer Test

Each gem has a unique refractive index:

  • Diamond: ~2.42
  • Moissanite: ~2.65
  • Quartz: ~1.54

Professionals use this to identify real vs synthetic stones.


 6. UV Light Fluorescence

Expose the gem to ultraviolet light:

  • Real diamonds and rubies may glow.
  • Fakes often don’t react or glow the right color.

 7. Check for Gemstone Certification

Always demand a lab-certified report from recognized institutes like:

  • GIA (Gemological Institute of America)
  • IGI (International Gemological Institute)
  • SSEF
  • Gubelin
