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.

Toi et Moi Marquise & Emerald Moissanite Necklace

About This Product

Two stones, one story — this Toi et Moi necklace sets a marquise-cut moissanite shoulder to shoulder with an emerald-cut moissanite, a pairing long worn to symbolize two souls leaning into one another. The marquise tapers to brilliant points and throws sharp, lively fire, while the emerald cut steps light into long, mirror-clean flashes — two contrasting personalities held in a single centered station. Both stones are DEF colorless with VVS clarity and together total about 3 carats DEW (moissanite is measured in diamond-equivalent weight because it is less dense than diamond, so the carat figure tracks visual size, not mass). Moissanite's 2.65 refractive index out-fires diamond's 2.42 for noticeably more rainbow sparkle, and at 9.25 on the Mohs scale it resists daily scratching and scuffing. Each stone sits in a slim single-prong setting that keeps the metal minimal and lets light flood in from every angle, and the pair is fixed as a fixed pendant on a delicate cable chain so it always faces forward and never spins. Styling note: the asymmetric two-stone silhouette reads as quietly modern rather than traditional, so it layers beautifully over a crew neck for everyday wear yet stands alone at a dinner or wedding. The warm 18K yellow-gold plating over 925 sterling silver flatters warm and neutral skin tones especially well. It makes a meaningful anniversary, engagement-adjacent, or milestone gift for someone who likes a story behind their jewelry. Spec: marquise + emerald-cut moissanite, DEF color, VVS clarity, ~3ct DEW total, 18K yellow-gold-plated 925 sterling silver, fixed cable-chain station.
