Is moissanite a real diamond?

Moissanite is not a diamond—it's a distinct gemstone with its own unique properties. Originally discovered in a meteor crater in 1893, today's moissanite is lab-created. It actually has more brilliance and fire than diamonds due to its higher refractive index (2.65 vs 2.42), while being nearly as hard (9.25 vs 10 on the Mohs scale).

Will moissanite pass a diamond tester?

Standard diamond testers measure thermal conductivity, and moissanite often passes these tests because both stones conduct heat similarly. Advanced testers that measure electrical conductivity can distinguish between them. We believe in transparency—our moissanite is beautiful in its own right.

Does moissanite get cloudy over time?

No, moissanite does not get cloudy, lose its sparkle, or change color over time. It's a stable, durable gemstone that maintains its brilliance for a lifetime with proper care. Unlike some simulants, moissanite is highly resistant to scratching, heat, and everyday chemicals.

Can I wear moissanite jewelry every day?

Absolutely! With a hardness of 9.25 on the Mohs scale (second only to diamond), moissanite is extremely durable and perfect for everyday wear, including engagement rings. We recommend removing jewelry during activities involving harsh chemicals or extreme impact.

What is your return policy?

We offer a 90-day worry-free return policy. If you're not 100% satisfied with your purchase, you can return it within 90 days for a full refund. All our moissanite jewelry also comes with a lifetime warranty covering manufacturing defects and stone clouding.

Heart-Cut Moissanite Solitaire Pendant Necklace | 0.8ct

About This Product

Pure romance, cut into a single stone. This pendant centers one heart-shaped moissanite of roughly 0.8 carat (DEW), measuring close to 6mm across, held in slim three-prong claws that let light flood every facet from edge to edge. The heart is one of the most demanding cuts to execute cleanly, and moissanite rewards the precision: with a refractive index of 2.65 against diamond's 2.42, the stone throws noticeably brighter fire, and its DEF-range colorlessness with VVS clarity keeps the face crisp and icy-white in the photo. There are no side stones to compete -- just one luminous heart suspended from a fine cable chain, so the silhouette carries the whole piece. The setting is finished in warm yellow gold over 925 sterling silver, the polished bail echoing the curve of the stone above it. Styling take: heart solitaires read sweetest worn solo at the collarbone, where the point sits clean against skin; layer it over a slightly longer plain chain only if you want a little length contrast without crowding the motif. It is an easy anniversary, Valentine's, or just-because gift precisely because it says one thing and says it well. At 9.25 on the Mohs scale moissanite resists the daily scuffs that dull softer stones, so this is a piece that can be worn every day rather than saved for occasions, holding its sparkle through years of wear. Specs: heart-cut moissanite, ~0.8ct DEW (~6mm), DEF color, VVS clarity, refractive index 2.65, 9.25 Mohs; three-prong setting; 925 sterling silver plated in yellow gold; fine cable chain.
