Moissanite vs Lab Grown Diamonds

We sell both — so here is an honest comparison to help you pick the stone that is right for you.

Two Different Stones

Lab Grown Diamond is a real diamond: pure carbon, grown in a lab, IGI certified. Moissanite is a different gemstone made of silicon carbide. It was first found in a meteor crater and is now created in labs. Both are beautiful, durable and conflict-free — they simply sparkle differently and sit at different price points.

Side-by-Side Comparison

Lab Grown Diamond Moissanite
What it is Real diamond (carbon) Separate gemstone (silicon carbide)
Hardness (Mohs) 10 — the hardest 9.25 — extremely hard, great for daily wear
Sparkle Bright white brilliance with balanced fire More fire — stronger rainbow flashes, especially in sunlight
Refractive index ≈ 2.42 ≈ 2.65
Certification IGI certified GRA certificate available on request
Diamond tester Tests as diamond Passes most standard thermal testers; electrical/multi-testers can identify it

How They Look Different

Side by side, moissanite shows more colourful "disco-ball" flashes because it disperses light more than diamond. A lab grown diamond shows crisper white sparkle with softer colour flashes. Neither is better — it is about which look you love. In everyday indoor light, most people cannot tell them apart at a glance.
