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.

3ct Round Moissanite Solitaire Ring | Marquise Accents

About This Product

A commanding 3ct (DEW) round-brilliant moissanite anchors this solitaire, measuring roughly 9.5mm across and seated high in a sculpted four-prong basket. Its 2.65 refractive index pulls noticeably more fire from every light source than a 2.42 diamond, so the stone throws broad flashes of color across the room rather than the cooler, more contained return of a mined diamond. What sets the design apart is the shoulders: instead of a plain shank, a single-file line of alternating marquise and round accents steps down each side, spacing the sparkle like a string of beads toward the center. The effect is a classic raised-solitaire silhouette with a quietly vintage, hand-set feel that flatters longer fingers and reads larger than its carat weight on the hand. Stylist's note: the spaced shoulder accents make this an easy ring to stack with a thin plain band, and the open gallery keeps the center stone the clear focal point under any lighting. The center is graded DEF colorless and VVS clarity, with a hardness of 9.25 on the Mohs scale, so it resists everyday scratching and holds its polish for years of daily wear. Built in 925 sterling silver under bright 18K yellow-gold plating, it suits engagements, anniversaries, or a self-purchase statement piece without the price of a natural stone. Available in yellow-gold and white-gold (rhodium) finishes and ring sizes 6 through 9. Spec block: 3ct DEW round moissanite (~9.5mm), DEF color, VVS clarity, refractive index 2.65, 9.25 Mohs; marquise-and-round accent shoulders; 925 sterling silver, 18K gold or rhodium plating.
