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 |
