The Best Diamond Alternative Ever Created
Hand-cut, one-of-a-kind stones that outshine diamonds.
Most jewelers treat moissanite as a generic diamond alternative. At MOISI, we do things differently. Every MOISI stone is individually hand-cut by master artisans, calibrated for maximum brilliance, fire, and durability. The result is a stone that doesn’t just rival diamonds — it surpasses them. No two MOISI stones are ever exactly alike.
What is Moissanite
Moissanite was first discovered in 1893 by Henri Moissan, a French chemist who later won the Nobel Prize. He found tiny crystals of silicon carbide in a meteor crater — and the gemstone was named moissanite in his honor.
Natural moissanite is extremely rare — far rarer than diamonds. In fact, diamonds maintain their aura of
rarity only through inflated pricing and controlled supply. Moissanite, on the other hand, offers true rarity
without manipulation, making it one of the most extraordinary gemstones in existence.
The Shiniest Gemstone — Moissanite has the highest refractive index of all gemstones (2.65–2.69),
reflecting more light and fire than diamond.
Durability — At 9.25 on the Mohs scale, it is the second hardest gemstone after diamond, designed for
daily wear that lasts a lifetime.
Forever Brilliant — Unlike other stones, moissanite never clouds, dulls, or loses its sparkle.
The MOISI Difference
Not every moissanite is created equally. Quality varies greatly, and most stones are machine-cut in bulk
with little attention to detail. At MOISI, we do things differently:
• Hand-Cut Stones — Every MOISI stone is individually hand-cut by master artisans. This gives us
complete control over symmetry, proportions, and facet precision.
• Unlimited Possibility — Hand cutting means we can create anything you imagine — from traditional
round brilliants to unique bespoke cuts.
• Consistent Brilliance — By refining each facet by hand, we ensure maximum light return and fire. No shortcuts, no compromises.
Performance & Durability
• Second Only to Diamond — At 9.25 Mohs, moissanite is harder than sapphires, rubies, and emeralds. It is a true heirloom gemstone built for generations.
• Forever Sparkle — Unlike other stones, moissanite never clouds, dulls, or fades. Its brilliance remains just as radiant decades from now.
Value & Security
Diamonds lose value the moment you buy them. MOISI jewelry doesn’t. With our lifetime buy-back
promise, your piece always retains its worth — beauty you can wear, and security you can hold.
And because moissanite is built to endure, it isn’t just jewelry for today. It’s an heirloom for tomorrow.
What better to pass down than something both sparkly and ethical?
