Why Choose Moissanite?
Why Moissanite?
Moissanite is the world's most brilliant gemstone — and it's not even close. Originally discovered in 1893 by Nobel Prize-winning chemist Dr. Henri Moissan in a meteorite crater, moissanite today is lab-created to exacting standards, delivering exceptional beauty with zero ethical compromise.
Unmatched Brilliance & Fire
Brilliance is determined by a gemstone's refractive index (RI) — the measurement of how much light bends as it passes through the stone. Moissanite has a refractive index of 2.65, compared to diamond's 2.42. This means moissanite bends more light, producing more sparkle and rainbow fire than a diamond of equal size.
Fire — the colorful flashes of light you see when a stone moves — is measured by dispersion. Moissanite's dispersion is 0.104, more than 2.4 times that of diamond (0.044). The result: a stone that dances with color in any light.
Exceptional Hardness & Durability
On the Mohs scale of mineral hardness, moissanite scores 9.25 — second only to diamond at 10. This makes moissanite one of the hardest substances on Earth, highly resistant to scratching, chipping, and breaking. It's a gemstone built for everyday wear, not just special occasions.
Moissanite vs. Diamond vs. Cubic Zirconia
| Property | Moissanite | Diamond | Cubic Zirconia |
|---|---|---|---|
| Refractive Index | 2.65 | 2.42 | 2.15 |
| Hardness (Mohs) | 9.25 | 10 | 8.0–8.5 |
| Fire Dispersion | 0.104 | 0.044 | 0.058 |
| Durability | Excellent — lifetime stone | Excellent — lifetime stone | Fair — clouds and scratches over time |
| Origin | Lab-created | Mined or lab-created | Lab-created |
| Ethical & Conflict-Free | Always | Varies by source | Always |
| Approximate Price (1ct equivalent) | $89–$300 | $3,000–$15,000+ | $10–$30 |
AGL Certification
Every CARISSIE moissanite stone comes with a certificate from the American Gemological Laboratories (AGL), one of the most respected independent gemological labs in the United States. Your AGL certificate verifies:
- Stone type and authenticity (confirmed moissanite)
- Cut grade and quality
- Carat weight equivalent
- Color and clarity grades
This certificate is your assurance that you're receiving a genuine, high-quality gemstone — not a lesser substitute.
Ethical & Sustainable
Unlike mined diamonds, moissanite is created in controlled laboratory environments with minimal environmental impact. There is no mining, no displacement of communities, and no risk of conflict sourcing. When you choose moissanite, you choose:
- Zero mining impact: No open-pit mines, no habitat destruction, no water pollution.
- Guaranteed conflict-free: Lab-created means no ethical ambiguity about sourcing.
- Sustainable production: Significantly lower carbon footprint compared to diamond mining.
- Transparent pricing: Without the artificial scarcity of mined diamonds, moissanite is priced based on its actual cost of production — not inflated by supply chain markups.
The Bottom Line
Moissanite isn't a diamond substitute — it's a superior alternative for anyone who values brilliance, durability, ethics, and value. It outperforms diamond in fire and sparkle, matches it in everyday wearability, and does it all at a fraction of the cost.
