White Gemstone Jewelry

Moissanite is the most popular white gemstone, valued for its exceptional fire and brilliance, Mohs 9.25 hardness, and accessible price as a diamond alternative. White sapphire is the most popular natural white gemstone at Mohs 9, while white topaz and moonstone offer additional white and clear options. All are set across Aquamarise® white gemstone jewelry.

Clear or colorless gemstones include moissanite, white sapphire, white topaz, and clear quartz. Moissanite and white sapphire are the most popular clear gemstones for rings because they resemble diamonds at a more accessible price. Explore our moissanite engagement rings and white sapphire rings.

Moissanite is the best white gemstone for engagement rings, offering more fire than diamond at Mohs 9.25 and excellent value. White sapphire is the best natural white option at Mohs 9, with a softer, more subtle sparkle. Explore our moissanite engagement rings and white sapphire rings.

White sapphire is a natural colorless corundum (Mohs 9) with a subtle, soft sparkle, and it does not test as diamond. Moissanite is lab-created (Mohs 9.25) with much more fire and brilliance, often exceeding diamond, and comes with a GRA certificate. White sapphire suits understated looks; moissanite suits maximum sparkle.

Clean with warm water, mild soap, and a soft cloth. Moissanite and white sapphire tolerate daily wear and cleaning well; moonstone is softer and should avoid hard knocks and ultrasonic cleaning. See our jewelry care guide.

Sterling silver is the entry tier, 14K gold vermeil sits in the middle, and solid gold is the heirloom tier, with price moving by stone size, cut, setting complexity, and metal. Moissanite and white topaz are the most accessible of the white stones, while natural white sapphire and solid gold settings sit higher. Our precious metal guide explains what each metal adds.

Three. 925 sterling silver is a solid alloy of 92.5% silver and 7.5% copper, finished in rhodium for a bright white surface. 14K gold vermeil bonds a 2.5 micron layer of 10K-or-finer gold over that same sterling core, the standard set by the US FTC. Solid 14K gold is 58.5% pure and stamped 585. Solid gold and platinum pieces are made to order in three to six weeks. See our precious metal guide.

Hardness runs from Mohs 9.25 down to 6. Moissanite, a silicon carbide first identified by Henri Moissan in the Canyon Diablo crater in 1893, sits at 9.25 with a refractive index of 2.65 against diamond’s 2.42. White sapphire is corundum at Mohs 9, white topaz at 8, clear quartz at 7, and moonstone, an orthoclase feldspar, at 6 to 6.5. The harder stones suit daily wear; moonstone prefers protective settings.
