How to Tell if Moissanite is Real: Red Flags to Watch For!

I’ve always been captivated by Moissanite’s brilliance and affordability. However, I quickly learned that not all moissanite is created equal. Through extensive research and personal experience, I discovered how to tell if moissanite is real. 

I’m excited to share my knowledge with you, providing the information you need to make a confident decision when purchasing a moissanite locket or exploring this gemstone’s unique properties. 

Join me as we uncover the tips and tricks to ensure you invest in genuine, high-quality moissanite.

What is Moissanite?

Moissanite is a naturally occurring mineral composed of silicon carbide, first discovered by French scientist Henri Moissan in 1893. Due to its rarity in nature, nearly all moissanite used in jewelry today is created in laboratories. 

These lab-grown stones exhibit exceptional brilliance, fire, and durability, making them a popular choice for engagement rings, wedding bands, and other fine jewelry pieces.

Moissanite vs. Diamonds: Key Differences

While moissanite and diamonds may appear similar at first glance, there are several notable differences between these two gemstones:

  • Composition: Diamonds are made of pure carbon, while moissanite consists of silicon carbide.
  • Brilliance and Fire: Moissanite has a higher refractive index (2.65-2.69) and dispersion rate (0.104) than diamonds, resulting in more vibrant flashes of color and a brighter overall appearance.
  • Hardness: Diamonds rank a perfect 10 on the Mohs scale, while moissanite ranks 9.25, making it slightly less resistant to scratches and abrasions.
  • Color: High-quality diamonds are typically colorless, while moissanite may display a slight yellow or gray hue, particularly in larger stones or under certain lighting conditions.
  • Price: Moissanite is significantly more affordable than diamonds of comparable size and quality, making it an attractive option for budget-conscious shoppers.

While moissanite and diamonds may appear similar at first glance, there are several notable differences between these two gemstones. However, both offer unique advantages. Diamonds hold a traditional prestige, while moissanite brings exceptional brilliance at a more accessible price point.

How to Tell if Moissanite is Real? The Essential Methods

To make sure you’re buying real moissanite, think about using these ways to check:

  1. Certification: Always ask for a certificate from a well-known gem lab when buying moissanite from a trusted seller. This paper will prove that the stone has been checked and confirmed as real by someone else.
  2. Visual Inspection: Even though it’s not perfect, looking closely at your moissanite can give you good clues about whether it’s real. Check for lots of sparkles, a clear or almost clear color, and a slight doubling effect because of how moissanite bends light.
  3. Thermal Conductivity Testing: Moissanite conducts heat much better than most fake diamonds, like cubic zirconia (CZ). A skilled jeweler can use a special tool to quickly tell the difference between moissanite and other fakes.
  4. Electrical Conductivity Testing: Unlike diamonds, which let electricity flow through them, moissanite does not. A tool that tests electrical conductivity can be used to identify moissanite by seeing how it reacts to an electric current.
  5. Refractive Index Testing: Moissanite has a higher refractive index (2.65-2.69) than diamonds (2.42), which is why it’s so incredibly sparkly. A tool called a refractometer can measure this and give a reliable hint about what the stone is.
  6. Professional Gemological Testing: For the most certain answer, have your moissanite looked at by a qualified gemologist or a trusted jewelry lab. They have special tools and methods, like spectroscopy and microscopic analysis, which can definitely identify moissanite and rule out any possible fakes.

Assessing Moissanite Quality

When evaluating the quality of a moissanite gemstone, consider the following factors:

  • Cut: A well-cut moissanite will have precise faceting, excellent symmetry, and optimal proportions, enhancing its brilliance and fire.
  • Clarity: Look for a stone that appears clean and transparent to the naked eye, with minimal inclusions or blemishes.
  • Color: The most desirable moissanite stones are colorless or near-colorless, with color grades ranging from DEF (colorless) to GHI (near-colorless).
  • Carat Weight: Consider the stone’s dimensions and overall proportions in relation to its weight. A well-cut moissanite will have a balanced size-to-weight ratio.

Avoiding Low-Quality Moissanite

Watch out for these red flags when shopping for moissanite jewelry:

  • Uneven or Poor Faceting: Inconsistent, asymmetrical, or poorly polished facets can indicate low quality.
  • Excessive Inclusions or Blemishes: A high-quality moissanite should be relatively clean and free of noticeable imperfections.
  • Strong Color Tints: A strong or uneven color tint can be a sign of low quality or a misrepresented stone.
  • Disproportionate Pricing: If a moissanite stone seems significantly underpriced, it may be a red flag for a low-quality or counterfeit stone.

How to Tell if Moissanite is Real (At Home)

While professional authentication is always recommended, there are a few simple tests you can perform at home to aid in how to tell if moissanite is real. These methods help distinguish moissanite from diamonds:

  1. The Fog Test: Breathe on the stone and observe how quickly the fog dissipates. Moissanite will dissipate the fog faster than a diamond due to its higher thermal conductivity.
  2. The Sparkle Test: Observe the stone under different lighting conditions, paying attention to the brilliance and fire. Moissanite will typically display more colorful flashes and a brighter overall appearance compared to a diamond.
  3. The Loupe Test: Use a 10x loupe to examine the stone closely. Moissanite may exhibit a subtle doubling effect due to its double refraction, which is not present in diamonds.

It’s important to note that these at-home tests are not foolproof and should be used in conjunction with professional authentication methods to ensure the accuracy of your assessment.


Knowing how to tell if moissanite is real is important when you want to buy this beautiful gemstone for your locket or other jewelry.

To make a smart choice and pick a real, high-quality moissanite you’ll love for years, you should:

Understand the main differences between moissanite and diamonds. Learn about the different ways to check if a moissanite is real. Look at the overall quality of the stone

Always buy from trusted sellers and ask for a certificate. If you’re still unsure, don’t be afraid to get it tested by a professional gemologist for the most reliable results.

You’re now well-equipped to navigate the world of moissanite with confidence and find the perfect stone to suit your style and budget.
