What is Moissanite? Pros, Cons & Is It Worth Buying (2026 Guide)

What is Moissanite?

Moissanite is a lab-created gemstone made from silicon carbide (SiC), known for its exceptional brilliance, durability, and affordability. Originally discovered in a meteor crater by French scientist Henri Moissan, natural moissanite is extremely rare, so nearly all moissanite used in jewelry today is lab-grown.

With a hardness of 9.25–9.5 on the Mohs scale, moissanite is one of the hardest gemstones available, second only to diamonds. This makes it highly resistant to scratches and ideal for everyday wear.

Moissanite vs Diamond: What’s the Difference?

• Price: Moissanite costs about 80–90% less than diamonds
• Brilliance: Moissanite has more fire (rainbow sparkle)
• Hardness: Diamond (10) vs Moissanite (9.25)
• Origin: Moissanite is lab-grown, diamonds are mined or lab-grown

To the naked eye, moissanite looks very similar to a diamond, making it a popular alternative for engagement rings and fine jewelry.
