More Light. More Brilliance. By Design.
A gemstone's brilliance is determined by its refractive index — how sharply it bends light as it enters and exits the stone. Moissanite's refractive index is 2.65. Diamond's is 2.42.
That difference is not subtle. When light enters a moissanite, it bends more dramatically, creating brighter flashes and more intense sparkle than any other gemstone on earth.
Moissanite vs. The Rest
| Gemstone | Refractive Index | Hardness (Mohs) | Fire (Dispersion) | Origin |
|---|---|---|---|---|
| Moissanite (ilussa) | 2.65 | 9.25 | 0.104 | Lab-created |
| Diamond | 2.42 | 10 | 0.044 | Mined |
| Sapphire | 1.77 | 9 | 0.018 | Mined |
| Ruby | 1.77 | 9 | 0.018 | Mined |

Lab-Created. Conflict-Free. Always.
Every moissanite at ilussa is grown in a controlled laboratory environment — no mining, no conflict, no environmental destruction. The stone was first discovered in 1893 by Nobel Prize-winning chemist Henri Moissan in a meteorite crater. Today's moissanite is entirely lab-created.
Zero Mining
No land disruption, no mining communities displaced, no environmental footprint from extraction.
Conflict-Free
100% lab origin means zero supply chain risk. Every stone traceable from creation to your hand.
Certified Quality
Stones over 0.3 carats include a certificate verifying stone properties and quality grade.
Lifetime Durability
At 9.25 Mohs, moissanite is harder than any gemstone except diamond — built to last generations.
ilussa Certification: All qualifying ilussa moissanite stones over 0.3 carats include a certificate of gemstone quality, verifying the stone's properties, grade, and origin.
