Lab-grown diamonds and moissanite are both popular alternatives to natural diamonds, but they differ significantly in composition, properties, and appeal. Here's a concise comparison based on available information:

1. Composition

  • Lab-Grown Diamonds: These are real diamonds, chemically and physically identical to mined diamonds. They are made of carbon atoms arranged in a diamond crystal structure, created in a lab using processes like High-Pressure High-Temperature (HPHT) or Chemical Vapor Deposition (CVD).
  • Moissanite: A gemstone made of silicon carbide (SiC), naturally occurring in minute quantities but almost always lab-created for jewelry. It’s not a diamond but a distinct gem with similar visual appeal.

2. Appearance

  • Lab-Grown Diamonds: Indistinguishable from natural diamonds to the naked eye. They have the same sparkle, fire, and brilliance, graded using the same 4Cs (cut, color, clarity, carat).
  • Moissanite: Mimics diamonds but has more colorful sparkle (higher dispersion, creating rainbow-like flashes). Some may notice a slight difference under certain lighting, especially in larger stones. Moissanite can appear less "white" than diamonds, sometimes showing a faint yellow or green tint.

3. Hardness and Durability

  • Lab-Grown Diamonds: Score 10 on the Mohs scale, the hardest known material, highly resistant to scratches and wear.
  • Moissanite: Scores 9.25-9.5 on the Mohs scale, very durable but slightly less hard than diamonds, making it more prone to scratches over time.

4. Cost

  • Lab-Grown Diamonds: Significantly cheaper than mined diamonds (30-50% less, depending on size and quality), but more expensive than moissanite. For example, a 1-carat lab-grown diamond might cost $1,000-$3,000, depending on quality.
  • Moissanite: Much more affordable, often 10-20% of the cost of a natural diamond. A 1-carat moissanite can cost $300-$600.

5. Ethical and Environmental Impact

  • Lab-Grown Diamonds: Generally considered more ethical and eco-friendly than mined diamonds, as they avoid mining’s environmental damage and potential human rights issues. However, production requires significant energy, though some labs use renewable sources.
  • Moissanite: Also ethically produced, as it’s lab-created with minimal environmental impact. No mining is involved, making it a sustainable choice.

6. Resale Value and Perception

  • Lab-Grown Diamonds: Retain some resale value, though less than natural diamonds. They’re increasingly accepted in the market but may still carry a perception of being "less prestigious" by some traditionalists.
  • Moissanite: Little to no resale value. Often seen as a budget-friendly diamond alternative, but it’s not a diamond, which may affect its perceived value in fine jewelry.

7. Certification and Identification

  • Lab-Grown Diamonds: Often come with certifications from gemological institutes (e.g., GIA, IGI) specifying they’re lab-grown. They require specialized equipment to distinguish from natural diamonds.
  • Moissanite: Easily identified by gemologists due to its different optical properties (e.g., double refraction). Certifications are less common but available from some retailers.


🔹 Brilliance

  • Lab Diamond: Softer light reflections, natural look.

  • Moissanite: Higher brilliance (2.65 RI) with colorful fire, sometimes seen as “too sparkly.”

🔹 Weight

  • Moissanite is lighter than diamonds. A 1-carat moissanite will look slightly bigger than a 1-carat lab diamond.

Gem Size Equivalent Weight
1.0 ct Lab Diamond 6.5 mm 1.00 ct
1.0 ct Moissanite 6.5 mm ~0.88 ct
