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.

Moissanite Key Pendant Necklace | 0.5ct Silver

About This Product

A key has long signaled trust, promise, and the unlocking of something meaningful, and this sterling silver key pendant carries that sentiment with a single brilliant-cut moissanite set into its oval bow. The stone is held in a four-prong floating mount at the heart of the key head, where it catches the light against the polished open bezel. Moissanite returns a refractive index of 2.65 versus a diamond's 2.42, so the fire here reads broader and more rainbow-flecked than a comparable colorless diamond. At roughly 0.5ct DEW (about 5mm round), it is a balanced everyday size that sits cleanly along the collarbone on the included cable chain. Spec block: Stone: Moissanite, 0.5ct DEW / 5mm round. Cut: Round brilliant, Excellent. Color: DEF colorless (Stone Color White). Clarity: VVS. Metal: 925 sterling silver. Setting: Four-prong floating mount within an oval key bow. Chain: Cable. The key silhouette, polished shaft and notched bit make this a versatile unisex piece, equally at home layered over a knit or worn solo on a longer chain. Moissanite's 9.25 Mohs hardness means the stone resists the scuffs and abrasions a daily-worn pendant inevitably meets, while the sterling setting keeps the design lightweight against the skin. To keep it bright, wipe the silver with a soft polishing cloth and store it away from perfume and lotions, which dull the metal over time. It makes a thoughtful gift for a graduation, a new home, a relationship milestone, or anyone who simply appreciates symbolic jewelry that carries real, lasting sparkle.
