What is Moissanite?

Moissanite is a silicon carbide gemstone commonly chosen as a diamond alternative due to its exceptional brilliance, vibrant color dispersion, and durability—all at a significantly lower cost. While naturally occurring moissanite is extremely rare, most of the stones available today are lab-created, offering a budget-friendly and ethical option for those who admire the look of natural diamonds.

How Does it Compare?

Moissanite is nearly as hard as a diamond, boasting a 9.25 rating on the Mohs scale—just shy of a diamond’s perfect 10. Though both gemstones are exceptionally durable, moissanite distinguishes itself with greater brilliance. Its higher refractive index means it exhibits more intense color dispersion, or "fire," resulting in a sparkle that often surpasses that of a diamond.


 Gem Name Refractive Index Hardness (Mohs) Key Features Durability
Cubic Zirconia 2.15 - 2.18 8 - 8.5 Great value, lab-created, low environmental impact, ethically produced Very Good
Lab Diamond 2.42 10 Timeless appearance, lab-grown, sustainable, ethically sourced Excellent
Mined Diamond 2.42 10 Natural origin, traditional appeal, certification recommended Excellent
Moissanite 2.65 - 2.69 9.25 Most brilliant, lab-grown, eco-conscious, ethically made Excellent
