What Is a Round Brilliant Cut Moissanite?
A round brilliant cut moissanite is a lab-created gemstone cut into a precise circular shape with fifty-seven or fifty-eight facets. These facets are mathematically aligned to maximize light return, producing extraordinary sparkle and rainbow fire.
Unlike generic round cuts, the brilliant cut is engineered specifically to enhance optical performance. When applied to moissanite—already known for its high refractive index—the result is breathtaking luminosity.
History of the Round Brilliant Cut
The round brilliant cut evolved over centuries, with major advancements in the early twentieth century when gem cutters began using mathematical formulas to maximize brilliance. While originally perfected for diamonds, this cut found an even more dramatic expression in moissanite.
Moissanite’s unique optical properties allow the round brilliant cut to exceed traditional sparkle expectations, giving it a modern edge while preserving timeless aesthetics.
The Science Behind Its Brilliance
Brilliance refers to white light reflection, fire to rainbow dispersion, and scintillation to sparkle movement. Moissanite excels in all three.
- Higher refractive index than diamond
- Exceptional light dispersion
- Sharp facet junctions for dynamic sparkle

Moissanite Fire vs Diamond Sparkle
Moissanite produces more colorful fire than diamonds due to higher dispersion. While diamonds reflect mostly white light, moissanite offers vivid flashes that many modern buyers adore.
Durability & Everyday Wear
With a Mohs hardness of 9.25, round brilliant moissanite is ideal for daily wear. It resists scratching, chipping, and clouding far better than many natural gemstones.
Ethical & Sustainable Advantages
Moissanite is lab-created, meaning no mining, no environmental destruction, and no ethical uncertainty. This makes it a conscious luxury choice for modern buyers.
Value & Cost Efficiency
Round brilliant cut moissanite offers exceptional visual size and sparkle at a fraction of the cost of traditional diamonds. This allows buyers to invest in larger stones or superior settings without compromise.
