Engagement Rings
Moissanite Engagement Rings — But Diamond-Grade.
Not all moissanite is created equal. Quorri's exclusive ATERNA® Gen 4 and LUXE® Gen 3 represent the next generation of diamond-grade moissanite — engineered for superior brilliance, exceptional durability, and breathtaking beauty at a fraction of the cost of a mined diamond.
Why Quorri Moissanite Is Different
When most people search for moissanite, they find the same standard silicon carbide gemstone sold everywhere. At Quorri, we go further.
Our exclusive ATERNA® Gen 4 and LUXE® Gen 3 are proprietary diamond-grade moissanite gems — superbly engineered in our state-of-the-art laboratories using an advanced next-generation formula that goes far beyond what traditional moissanite can offer. From hardness and colour stability to cut precision and brilliance, every aspect has been elevated to meet diamond-grade standards.
The result? A gemstone that not only rivals a mined diamond in beauty — it outperforms standard moissanite in every meaningful way.
Diamond-Grade Moissanite
What Is ATERNA® Gen 4?
Not standard moissanite. Something far beyond it.
ATERNA® Gen 4 is Quorri's exclusive, proprietary Diamond-Grade Moissanite — a next-generation evolution of the Silicon Carbide crystal family, engineered from the ground up for superior performance. While standard moissanite has remained largely unchanged, our team spent years developing a proprietary Gen 4 formula — a unique blend of SiC and carbon — that delivers harder, more colourless, and more brilliant stones than anything standard moissanite can offer. The result is a gem that doesn't just compare to a mined diamond. In many ways, it surpasses it.

How ATERNA® Gen 4 goes beyond standard moissanite
✓
Harder — 9.50 Mohs vs standard moissanite's 9.25 Mohs, for greater scratch resistance and everyday durability.
✓
More colourless — D/E colour grade vs standard moissanite's H–J near-colourless, for a purer, more radiant appearance.
✓
Permanently colourless under heat — standard moissanite can turn yellow when exposed to high temperatures. ATERNA® Gen 4 never does.
✓
Superior cut — every ATERNA® stone is hand-cut to Ideal diamond standards, while standard moissanite is typically cut to moissanite-only proportions that fall short of diamond-grade brilliance.
✓
Passes diamond tests — thermal conductivity, fog, and transparency tests. Standard moissanite often fails one or more of these.

LUXE® Gen 3 matches the durability of traditional moissanite at 9.25 Mohs while surpassing it through its advanced Gen 3 formulation and meticulous finishing. Harder than sapphire, ruby, and emerald — engineered for a lifetime of beautiful, worry-free everyday wear.
The finest diamonds in the world fall between D and F on the GIA colour scale. LUXE® Gen 3 is exclusively created at E/F — near the absolute top of the colourless range — delivering breathtaking purity, radiance, and striking visual clarity that outperforms standard moissanite.
LUXE® Gen 3's advanced Gen 3 formula delivers significantly better heat stability than standard moissanite. Where standard moissanite can develop a yellow or greenish tint under high temperatures, LUXE® Gen 3 maintains its beautiful colourless appearance.
Every LUXE® stone is hand-cut by our master diamond cutters to Ideal diamond proportions, capturing 100% of available light. With perfectly symmetrical facets and increased surface area, LUXE® delivers maximum brilliance, exceptional fire, and endless sparkle.
The Science Behind Gen 3
LUXE® Gen 3 is engineered using our advanced reformulated Diamond-Grade moissanite formula — a proprietary blend of Silicon Carbide and elements — combined with a precision HPHT process that produces crystals closely resembling uncut diamonds in their raw state. Each flawless crystal then undergoes precise laser separation, ensuring only the finest stones advance to our cutting facility. There, our world-renowned master cutters shape and polish each stone by hand to Ideal proportions — a process that guarantees every LUXE® gem meets our uncompromising standard of excellence.
ATERNA CAN PASS DIAMOND TESTING
Diamond Testing — What to Expect From Your Gem
On standard thermal diamond testers, both ATERNA® Gen 4 and LUXE® Gen 3 can test positive due to their high carbon content and diamond-like heat signature. Advanced multi-testers with moissanite detection may distinguish them — which simply confirms what they are: premium Diamond-Grade Moissanite, engineered to the highest standard in the world.
Passes The Fog Test
Diamonds conduct and disperse heat almost instantaneously. To test a stone, simply breathe on it the way you would fog a mirror — if it stays fogged for even a couple of seconds, it's unlikely to be a diamond. Both ATERNA® Gen 4 and LUXE® Gen 3 disperse the heat from your breath instantly, just like a real diamond, leaving no fog whatsoever. Standard moissanite frequently fails this test.
Passes The Transparency Test
A genuine diamond refracts light so intensely that it is impossible to see through it — even newspaper print held beneath the stone becomes completely unreadable. Both ATERNA® Gen 4 and LUXE® Gen 3 bend and refract light so sharply that print beneath the stone disappears entirely — passing the transparency test with ease. This is a direct result of their Ideal diamond cut and advanced Diamond-Grade formula, and is a property standard moissanite cannot consistently replicate.
Beautiful Gems. No Cost to the Earth.
Responsibly crafted. Ethically yours.
Every ATERNA® Gen 4 and LUXE® Gen 3 gem is created entirely in our state-of-the-art laboratory — never mined, never at the expense of the earth or the people on it. No open pit mines. No displaced communities. No conflict. Just breathtaking gems engineered with the same care and precision we put into every ring we craft.
Choosing Quorri means choosing a gem you can wear with complete confidence — knowing your love story had zero environmental cost, and that somewhere, a polar bear is still resting on undisturbed ice.
Commonly Asked Questions
-
ATERNA® Gen 4 is Quorri's exclusive proprietary Diamond-Grade Moissanite — a next-generation evolution of the Silicon Carbide crystal family engineered for superior hardness, permanent colourlessness, and exceptional brilliance. At 9.50 Mohs and D/E colour grade, it is the most advanced moissanite gem available anywhere in the world.
-
LUXE® Gen 3 is Quorri's advanced Diamond-Grade Moissanite gem, engineered using a reformulated Gen 3 Silicon Carbide formula for exceptional brilliance, E/F colourlessness, and impressive 9.25 Mohs hardness — all at a remarkable price point that makes diamond-grade beauty accessible to everyone.
-
Both are Diamond-Grade Moissanite gems that far surpass standard moissanite — but ATERNA® Gen 4 is our pinnacle gem. It is harder (9.50 vs 9.25 Mohs), more colourless (D/E vs E/F), takes up to three months to produce, and remains permanently colourless even under heat — a property unique to Gen 4. LUXE® Gen 3 delivers outstanding diamond-grade quality at exceptional value.
-
Standard moissanite is a Silicon Carbide gem graded H–J colour (near-colourless), rated at 9.25 Mohs, and machine cut to moissanite-specific proportions that fall short of Ideal diamond standards. Both ATERNA® Gen 4 and LUXE® Gen 3 surpass standard moissanite in hardness, colour grade, hand-cut precision, heat stability, and diamond test performance — they are not the same product.
-
A mined diamond is 10 Mohs — the hardest substance on earth. ATERNA® Gen 4 comes closest at 9.50 Mohs, with D/E colourlessness and Ideal cut — rivalling a mined diamond in nearly every visible and measurable property at a fraction of the cost. Both gems pass thermal diamond testers, the fog test, and the transparency test.
-
Both ATERNA® Gen 4 and LUXE® Gen 3 pass standard thermal diamond testers, the fog test, and the transparency test. Only a trained gemologist using specialised multi-tester equipment can identify them as moissanite. To the naked eye — and in most testing scenarios — they are indistinguishable from a mined diamond.
-
Absolutely not. Both ATERNA® Gen 4 and LUXE® Gen 3 are Silicon Carbide-based Diamond-Grade gems with zero CZ content. They are in an entirely different category from cubic zirconia in terms of hardness, brilliance, durability, and longevity.
-
Yes — exceptionally so. ATERNA® Gen 4 at 9.50 Mohs and LUXE® Gen 3 at 9.25 Mohs are both well above the hardness threshold recommended for everyday wear jewellery. Only a diamond (10 Mohs) is harder. Both gems are scratch-resistant, durable, and designed to be worn and enjoyed for a lifetime.
-
Yes. Both ATERNA® Gen 4 and LUXE® Gen 3 are permanently colourless and will not yellow, fade, or change appearance over time. ATERNA® Gen 4 additionally maintains its colourlessness even when exposed to high heat — a property standard moissanite cannot guarantee.

Yes — completely. Both gems are created entirely in our laboratory. No mining, no environmental destruction, no conflict. Every Quorri gem is guaranteed to be ethically crafted and conflict-free.
