What Is Moissanite?
Moissanite is one of the most brilliant gemstones in the world — and one of the most misunderstood. Originally discovered in a meteor crater by Nobel Prize-winning scientist Henri Moissan in 1893, natural moissanite is incredibly rare. Today, virtually all moissanite used in jewelry is lab-created, making it an accessible and stunning alternative to diamonds.
But is moissanite the right choice for you? Let's break down the honest pros and cons.
The Pros of Moissanite
1. Exceptional Brilliance
Moissanite has a higher refractive index (2.65) than diamond (2.42), meaning it bends light more intensely and produces even more sparkle and fire. In certain lighting conditions, moissanite can outshine a diamond with its rainbow-like light dispersion.
2. Highly Affordable
Moissanite costs significantly less than diamonds — often 80–90% less than a comparable mined diamond and 50–60% less than a lab-grown diamond of the same size. This makes it an excellent choice for those who want a large, stunning stone on a budget.
3. Excellent Durability
Moissanite scores 9.25 on the Mohs hardness scale, making it the second hardest gemstone used in jewelry after diamond (10). It's highly resistant to scratching, chipping, and everyday wear — ideal for engagement rings and daily-wear jewelry.
4. Ethical and Sustainable
Since moissanite is lab-created, it is 100% conflict-free and has a minimal environmental footprint compared to mined gemstones. You can wear it with a clear conscience.
5. Near-Colorless Options Available
Modern moissanite is available in DEF color grades (near-colorless to colorless), making it virtually indistinguishable from a high-quality diamond to the naked eye.
6. Certified Quality
Quality moissanite comes with certification, so you know exactly what you're purchasing in terms of size, color, and cut quality.
The Cons of Moissanite
1. Different Light Performance
While moissanite's brilliance is stunning, its rainbow fire effect is more intense than a diamond's. In larger stones (over 1 carat), this can sometimes appear more "disco-like" rather than the classic white sparkle of a diamond. This is purely a matter of personal preference.
2. Not a Diamond
Moissanite is a diamond simulant, not a diamond. It is a completely different mineral (silicon carbide vs. carbon). If owning a genuine diamond is important to you symbolically or sentimentally, moissanite may not fulfill that desire.
3. Lower Resale Value
Like most gemstones, moissanite has a limited resale market. If investment value is a consideration, this is worth keeping in mind — though the same applies to most jewelry purchases.
4. Can Show a Slight Tint in Certain Lighting
Lower-grade moissanite (GHI color) can show a slight yellow or grey tint in certain lighting conditions. Always opt for DEF color grade moissanite for the most diamond-like appearance.
Who Should Choose Moissanite?
Moissanite is an excellent choice if you:
- Want maximum size and sparkle for your budget
- Prioritize ethical and sustainable sourcing
- Love intense brilliance and fire
- Are open to a gemstone that isn't a diamond
Who Should Choose a Lab-Grown Diamond Instead?
A lab-grown diamond may be a better fit if you:
- Want a real, certified diamond with the same properties as a mined diamond
- Prefer the classic white sparkle of a diamond
- Value the prestige and symbolism of a diamond
