Moissanite vs White Sapphire: Which Diamond Alternative Wins?

If you're shopping diamond alternatives, moissanite and white sapphire are the two names that come up most. They're both real, both cheaper than diamond, and they look quite different on a hand. Here's how to choose.

This is where they split. Moissanite has a very high refractive index and throws intense fire — lots of light and rainbow flash. White sapphire is more subdued; it has a soft, glassy, understated shine rather than a brilliant one. If you want maximum sparkle, moissanite; if you want quiet and vintage, sapphire.

Both are durable, but moissanite edges it: 9.25 on the Mohs scale versus white sapphire's 9. More importantly, white sapphire can look a little cloudy or 'wet' and tends to show buildup faster, needing more frequent cleaning to keep its modest sparkle. Moissanite holds its fire with less fuss.

Both are far cheaper than diamond and reasonably close to each other, though white sapphire is often a touch less. Given how similar the price is, the decision usually comes down to the look you want, not the cost.

Want brilliance, fire, and low maintenance? Moissanite. Want a soft, subtle, vintage glow and don't mind cleaning it more often? White sapphire. For most people chasing that diamond look, moissanite's sparkle and easier upkeep win.
