LAB-GROWN DIAMOND VS MOISSANITE
QUICK COMPARISON
LAB GROWN DIAMONDS
Pure carbon, same as mined diamonds. Hardness of 10 on the Mohs scale. The same optical properties and certified grading standards. A real diamond grown in a lab.
MOISSANITE
Produces 2.4× more fire than diamonds. Refractive index of 2.65 creates visible rainbow flashes. Sparkles strongly in all light. Silicon carbide crystal structure.
STONE COMPARISON
MOISSANITE
Higher fire dispersion than diamonds. More visible sparkle. Lower cost per carat.
LAB DIAMOND
Same composition as mined diamonds. Lab-grown without mining. Real diamond, different source.
THE FOUR C'S
Cut
How light moves through the stone. A well-cut stone reflects more light. This determines brilliance and sparkle.
Moissanite
Shows more rainbow fire than diamonds. Light disperses into visible color flashes. Sparkles strongly even in dim lighting.
Lab diamond
Cut with precision for maximum light return. The same brilliance as mined diamonds. Same optical properties, different origin.
Colour
The absence of color in a stone. Graded from D (no color) to Z (light yellow). Most differences invisible to untrained eyes.
Moissanite
We stock DEF color grades only. Some stones show faint blue or yellow tints under certain light. The strong brilliance usually masks these subtle tones.
Lab diamond
The same color range as mined diamonds. Every grade from D to Z available. Match stones precisely for multi-stone settings.
Clarity
Internal flaws and surface marks in the stone. Most are invisible without magnification. Fewer inclusions mean more light passes through.
Moissanite
Most are eye-clean with no visible flaws. Grown in controlled conditions with fewer inclusions. VS clarity or better is standard.
Lab diamond
Available in every clarity grade from flawless to included. Graded by the same standards as mined diamonds. Pick the clarity level you need.
Carat
Weight of the stone in carats. One carat equals 0.2 grams. Cut quality affects how large a stone looks at any weight.
Moissanite
A one-carat moissanite looks 15% larger than a one-carat diamond. Lower density means more surface area per carat. Bigger look at the same weight.
Lab diamond
Same weight and dimensions as mined diamonds. Measured by standard carat weight. One carat looks like one carat.
CONSUMER INSIGHTS
Practical facts about performance, cost, and real-world use. What you need to know before choosing.
Moissanite
Costs 80–90% less than equivalent diamonds. A one-carat moissanite costs what a quarter-carat diamond costs.
9.25 on the Mohs hardness scale. Hard enough for daily wear. Resists scratching in normal use.
Lab-grown with controlled processes. Lower environmental impact than mining. No supply chain concerns.
Higher refractive index creates more fire than diamonds. More visible rainbow flashes. Stands out in any light.
Lab diamond
Graded by the same standards as mined diamonds. GIA and IGI provide the same certification reports.
Cost 40–50% less than mined diamonds. Same chemical composition at a lower price point.
Pure carbon in a cubic crystal structure. The same physical and optical properties as mined diamonds.
Growing market acceptance. More jewelers stock them. More buyers choose them each year.
