LUXE® Gen 3 Diamond Grade Moissanite
Brilliant, ethical and unforgettable. Breathtaking beauty without the mined diamond price.
What Makes LUXE® Gen 3 Different
LUXE® Gen 3 is made for those who want exceptional performance and ethical origins. It offers diamond grade brilliance at a fraction of the cost, with more consistent colour, precision cutting and lasting fire than standard moissanite.
Available exclusively through Quorri and hand set in Canada in solid gold or 950 platinum.
What Is LUXE® Gen 3?
Not standard moissanite. A diamond-grade evolution.
LUXE® Gen 3 is Quorri's Diamond-Grade Moissanite: engineered to deliver extraordinary brilliance, lasting durability, and a truly colourless appearance at a fraction of the cost of a mined diamond. Built on an advanced proprietary Gen 3 formula: a refined blend of Silicon Carbide and 50% carbon, LUXE® Gen 3 achieves E/F colourless grading, VVS2 clarity, and a 9.25 Mohs hardness that surpasses sapphire, ruby, and emerald. The result is a diamond-grade gem with the look of a fine mined diamond and even more fire.
9.25 Mohs
Exceptional Hardness
Harder than sapphire, ruby, and emerald. Built for a lifetime of daily wear.
E/F Grade
Near-Top Colourless
Exclusively E/F colourless, near the absolute finest end of the international colour scale.
Ideal Cut
Maximum Brilliance
Hand-cut to Ideal diamond proportions by master cutters for maximum brilliance and fire.
How LUXE® Gen 3 goes beyond standard moissanite
✓
More colourless: E/F colour grade vs standard moissanite's H–J near-colourless, for a purer, more radiant appearance with no yellow or grey undertones.
✓
Higher clarity: VVS2 clarity grade, virtually flawless to the naked eye. Standard moissanite clarity varies significantly and is rarely disclosed.
✓
Superior cut: every LUXE® Gen 3 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.
✓
No CZ in the formula: LUXE® Gen 3 is a pure blend of 50% Silicon Carbide and 50% Carbon. Cubic zirconia is a softer material that can cloud and scratch over time, and it is not part of our formula.
✓
Passes diamond tests: thermal conductivity, fog, and transparency tests. Results vary with standard moissanite.

Engineered for Diamond Grade Brilliance
Every LUXE® Gen 3 stone begins in our Canadian laboratories, where an advanced HPHT (high pressure, high temperature) process produces our proprietary blend of silicon carbide and carbon. It gives each stone its E/F colourless grade, VVS2 clarity and 9.25 Mohs hardness.
Each raw crystal is precisely separated by laser, and only the highest graded stones move on. They go to our cutting facility, where master cutters shape and polish each one by hand to ideal diamond proportions. The result is radiance and brilliance meant to last a lifetime.
Ideal Cut, Handcrafted for Light
Every LUXE® Gen 3 gemstone is precision cut by our master artisans to ideal diamond proportions, the same standard used for the world's finest diamonds. Cut quality defines brilliance, because a stone cut too deep or too shallow lets light escape.
With LUXE® Gen 3, each facet is perfected to return as much light as possible as fire and scintillation. Each stone is a handcrafted work of art, symmetrical, diamond grade in performance and made to command attention in any setting.
Exclusively E/F Colourless
Colour is one of the most important quality factors in a diamond grade gemstone. The less colour a stone has, the purer and more brilliant it looks. The finest colourless stones achieve a D, E or F grade on the international colour scale, a standard first developed for diamonds.
Every LUXE® Gen 3 stone is created exclusively to E/F colourless grades, near the top of the range. Standard moissanite can carry subtle yellow or grey undertones, while LUXE® Gen 3 stays consistently colourless in sunlight and indoor light alike. Compare LUXE® Gen 3 colour grading with ATERNA® Gen 4 and mined diamonds.

View Full Stone ComparisonDoes LUXE® Gen 3 Pass Diamond Tests?
Positive Diamond Tester Result
Standard thermal diamond testers measure heat conductivity. Because LUXE® Gen 3 has a high carbon content and a heat signature close to a natural diamond, it registers as a diamond on most standard thermal testers.
Passes the Fog Test
Hold a stone close to your mouth and exhale gently. A genuine diamond clears almost immediately because it conducts heat so efficiently. LUXE® Gen 3 clears quickly, behaving much as a diamond does.
Passes the Transparency Test
Place printed text beneath a genuine diamond and it becomes unreadable, because the stone refracts light so powerfully. LUXE® Gen 3 produces the same result, thanks to its diamond grade formula and ideal cut.
LUXE® Gen 3: proven diamond grade performance
Responsibly Crafted and Conflict Free
Every LUXE® Gen 3 gemstone is grown in a controlled laboratory, with no mining and no excavation. Produced entirely above ground, it avoids the environmental impact of traditional diamond extraction.
Each stone is conflict free, ethically created and kinder to the planet, a reflection of your values as much as your style.

LUXE® Gen 3 is Quorri's diamond grade moissanite, a proprietary gemstone made from a blend of silicon carbide and carbon. It has a hardness of 9.25 Mohs, an E/F colourless grade, VVS2 clarity and a refractive index of 2.65 to 2.69, which gives it about 2.4 times the fire of a diamond. Every stone is hand cut to ideal diamond proportions. It isn't a cubic zirconia or a standard moissanite, and it's available exclusively through Quorri.
-
LUXE® Gen 3 rates 9.25 on the Mohs scale, harder than sapphire, ruby and emerald and second only to diamond at 10. That makes it one of the most durable gemstones for everyday wear in engagement rings, wedding bands and fine jewellery. Every stone is backed by our lifetime guarantee.
-
No. LUXE® Gen 3 is engineered to keep its colourless grade and fire for the life of the stone. It has no surface coating that can wear away, so what you see on day one is what you'll see decades later.
-
On most standard thermal diamond testers, LUXE® Gen 3 registers as a diamond because of its high carbon content and heat conductivity. Advanced multi-testers with moissanite detection can identify it as moissanite, which simply confirms what it is. It also passes the fog test and the transparency test, two common field tests for diamonds.
-
Both come from the silicon carbide family, but LUXE® Gen 3 is a proprietary reformulation. Every stone has an exclusive E/F colourless grade, while standard moissanite can show yellow or grey undertones. It's also cut to ideal diamond proportions by master cutters and has no cubic zirconia in its formula. See the details in our full stone comparison guide.
-
No. LUXE® Gen 3 contains no cubic zirconia. It's made from a proprietary blend of silicon carbide and carbon, which gives it its 9.25 Mohs hardness and diamond grade optical performance.
-
Yes. Every LUXE® Gen 3 stone is grown in a controlled laboratory, with no mining, no land excavation and no connection to conflict zones.
