Wholesale Moissanite Stones
Moissanite is a different mineral entirely from diamond — silicon carbide rather than carbon — with its own distinct optical signature. Its refractive index (2.65-2.69) is meaningfully higher than diamond’s (2.42), and its dispersion rate — the property responsible for colorful “fire” — is more than double diamond’s, at 0.104 versus 0.044. In practice, this means moissanite reads as more overtly colorful and prismatic under direct light, while diamond’s brilliance leans toward crisp white light return. Neither is objectively better; they’re genuinely different visual signatures, and increasingly, buyers actively choose moissanite for that rainbow “fire” rather than seeing it as a diamond substitute.
While diamonds are our core focus, OCS Diamond also sources and supplies loose moissanite in both white and fancy color options, under the same trade terms, dispatch process, and quality standards as our diamond stock. It’s a smaller part of what we do, but genuinely offered — not an afterthought — for buyers looking to diversify their offering without opening a separate supplier relationship.

Why Retailers Add Moissanite to Their Range
Moissanite occupies a genuinely different price and positioning tier than even lab-grown diamond — a meaningful gap that lets retailers serve budget-conscious buyers without competing against their own diamond inventory on price. Rather than a downgrade option, it’s increasingly marketed as its own deliberate choice: buyers who specifically want maximum visible sparkle, at accessible pricing, and who aren’t prioritizing diamond’s specific resale and cultural positioning. Offering both from a single supplier means you can serve both buyer types without managing two separate vendor relationships.
Moissanite vs Diamond - The Real Differences
| Property | Moissanite | Diamond |
|---|---|---|
| Composition | Silicon carbide | Carbon |
| Hardness (Mohs scale) | 9.25 | 10 |
| Refractive Index | 2.65–2.69 | 2.42 |
| Dispersion (fire) | 0.104 | 0.044 |
| Visual character | More colorful, prismatic “fire” | Crisp white brilliance |
Hardness is the one durability factor worth flagging directly: at 9.25, moissanite is still exceptionally hard — well above sapphire or ruby, and more than sufficient for daily wear jewelry — but it isn’t quite diamond’s 10. For retailers, this distinction matters mainly in how you position the stone to your customer: moissanite as a genuine, durable gemstone with its own optical identity, not as a “lesser diamond.
Frequently Asked Questions
They’re different minerals entirely — moissanite is silicon carbide, diamond is carbon. Moissanite has a higher refractive index and more than double diamond’s dispersion rate, giving it more visible colorful “fire,” while diamond shows a crisper white brilliance. Moissanite is also slightly softer (9.25 vs diamond’s 10 on the Mohs scale), though still exceptionally durable for daily wear.
Moissanite uses different grading conventions than diamond’s 4Cs system, though certification is available on request. Ask our team for current certification options for your specific order.
Contact our team to confirm current minimum order requirements for moissanite — terms may differ from our standard diamond MOQ given it’s a smaller part of our overall inventory.
