Moissanite is a lab-created gemstone made of silicon carbide. Originally discovered in a meteorite crater, it is one of the hardest gemstones on earth (9.25 on the Mohs scale) and is prized for its exceptional fire and brilliance — often exceeding that of a diamond.

Is moissanite a real gemstone?

Yes. Moissanite is a genuine gemstone with its own distinct chemical composition (silicon carbide). It is not a fake diamond — it is a different stone with unique optical properties, including higher fire and brilliance than a mined diamond.

What does GRA certified moissanite mean?

GRA (Gemological Research Association) is an independent gemological laboratory that certifies the quality and authenticity of moissanite stones. All Heritage & Co. moissanite comes with a GRA certificate confirming stone grade and characteristics.

How does moissanite compare to a diamond?

Moissanite has a higher refractive index than diamond, producing more fire and brilliance. It scores 9.25 on the Mohs hardness scale versus diamond's 10, making it highly durable for everyday wear. Moissanite is typically 80–90% more affordable than an equivalent mined diamond.
