If you are sourcing fashion jewelry for resale, the choice between moissanite and cubic zirconia (CZ) is one of the most consequential decisions you will make. Both are diamond simulants, both are affordable, and both sell well — but they behave very differently in terms of sparkle, cost, durability, and the customers they attract. This guide breaks down the practical differences so you can stock the right stone for the right price point.
Moissanite is silicon carbide, a lab-created mineral with a refractive index of roughly 2.65 — higher than diamond's 2.42. That high refractive index is why moissanite throws more "fire" (rainbow-colored flashes) than almost any other gemstone. It is also extremely hard, scoring 9.25 on the Mohs scale, just below diamond at 10.
Cubic zirconia is zirconium dioxide, a synthetic material first developed in the 1970s. It scores 8 to 8.5 on the Mohs scale and has a refractive index around 2.15. CZ looks bright and clean when new, but it is softer and more prone to scratching and clouding over time.
The visual difference is the first thing your customers will notice. Moissanite produces intense, almost disco-ball fire, especially under indoor lighting. Some buyers love this; others find it too colorful compared to diamond. CZ produces a more neutral white brilliance that mimics a well-cut diamond more closely in daylight.
For wholesale purposes, this matters because moissanite photographs extremely well — a real advantage for online sellers running paid ads or social media. CZ is subtler and often preferred by buyers who want a classic, understated look.
This is where the two stones diverge sharply. CZ is one of the cheapest gemstones on earth. A 1-carat equivalent CZ stone costs cents at factory level. Moissanite, while far cheaper than diamond, is still a premium material — a 1-carat equivalent moissanite can cost tens of dollars per stone depending on cut and clarity.
At China Jewelry Factory, both options are available across our 632 original styles, including necklaces, earrings, bracelets, rings, sets, pendants, anklets, and brooches. The practical implication: CZ suits high-volume, low-ticket lines; moissanite suits higher-margin statement pieces and bridal collections.
Durability is where CZ often disappoints. Because it is softer, CZ stones scratch, dull, and can develop a cloudy appearance with daily wear. In rings — especially engagement-style rings — CZ frequently needs replacing within a year or two.
Moissanite holds up far better. Its 9.25 Mohs hardness means it resists scratching, and it does not cloud over time. For buyers selling to customers who expect a piece to last, moissanite is the safer long-term choice.
It is worth noting that the metal setting matters just as much. Our titanium steel and 316L stainless steel pieces are hypoallergenic, nickel-free, and lead-free, with IP/PVD vacuum plating and 48-hour salt-spray tarnish testing. Pairing a durable stone with a durable setting is what keeps customers from returning items.
Demand patterns vary by region and channel:
A practical strategy for most wholesalers is to carry both: CZ for volume and trend pieces, moissanite for hero products and higher-margin SKUs.
When ordering from a factory, keep these points in mind:
If your customers are price-driven and you need fast turnover, CZ is the workhorse. If you want higher margins, better reviews, and products that survive daily wear, moissanite is worth the higher unit cost. Many successful buyers run both: CZ to drive traffic, moissanite to drive profit.
Based in Meilong, Haifeng County, Guangdong — China's fashion jewelry manufacturing hub — China Jewelry Factory produces both stone types across titanium steel, 316L stainless steel, sterling silver, gold-plated, pearl, and CZ/moissanite combinations.
