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.
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.

Why Retailers Add Moissanite to Their Range
Moissanite gives retailers another way to serve customers who want a highly expressive, sparkle-forward gemstone at a more accessible price point. Its stronger color dispersion creates a noticeably different visual effect, making it possible to offer something beyond the classic look of diamond while maintaining a premium jewelry presentation.
For retailers, this creates room for a distinct product tier rather than simply another variation of the same offering. Moissanite can appeal to buyers who prioritize visible fire, larger-looking stones, and accessible pricing, while your diamond collection continues to serve customers with different preferences and priorities.
With OCS Diamond, retailers can source moissanite alongside their existing diamond requirements, making it easier to broaden their assortment without adding unnecessary complexity to procurement.
Frequently Asked Questions
Moissanite and lab grown diamond are distinct gemstones with different optical characteristics. Moissanite is known for its stronger colorful fire and prismatic appearance, while lab grown diamond has a crisper brilliance. For retailers, the key distinction is that moissanite should be positioned as its own gemstone choice rather than simply as an alternative version of diamond.
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.
