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.

3 CT Marquise Moissanite Bypass Bridal Set

About This Product

A bypass bridal set built around a single elongated marquise moissanite, set on the diagonal so the pointed ends draw the eye lengthwise across the finger and make the hand look slimmer. Two pieces nest together: a solitaire engagement ring whose band splits and sweeps past the stone in claw prongs, and a matching contoured band that curves to hug the center, both lined with pave for a continuous ribbon of light. The center stone reads as a 3ct DEW marquise, roughly 14 x 7mm, large enough to carry the design without overwhelming a slender band. Moissanite earns its sparkle on the numbers: a 2.65 refractive index against a diamond's 2.42 throws noticeably more fire, so the long facets flash spectral color with every turn, while a 9.25 Mohs hardness stands up to daily wear at the desk, in the car, or on the go. The DEF colorless grade keeps the stone bright and white against warm gold, and VVS clarity means no inclusions interrupt the light. Stylist note: a diagonal marquise in a bypass mount is the move when you want a non-traditional silhouette that still photographs as a classic engagement-and-band pairing - wear both stacked for the wedding look, or the solitaire alone day to day. Crafted in 925 sterling silver finished with 18K yellow gold plating for a warm, vintage-leaning tone. Specs: 3ct DEW marquise (approx. 14 x 7mm), DEF color, VVS clarity, 2.65 RI, 9.25 Mohs; 925 sterling silver, 18K yellow gold plating; two-ring bridal set.
