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 Marquise Pendant Necklace | 925 Silver

About This Product

A marquise solitaire that draws the eye upward — the pointed-oval cut elongates the neckline while a pavé-set triangular bail adds a second flash of brilliance above the stone. Suspended from a fine cable chain, it reads delicate without disappearing, the layering-friendly proof being its compact 11.5mm x 5mm pendant footprint that sits flat against the collarbone. The center moissanite is held in a north-south prong setting, secured at both top and bottom so the long axis hangs true rather than twisting on the chain. Moissanite refracts light at an index of 2.65 — higher than diamond's 2.42 — which is why the marquise's tapered ends throw the lively, rainbow-edged sparkle you can see catching the metal in the photo. It grades DEF colorless and VVS clarity, and at 9.25 on the Mohs scale it resists the everyday scratches and clouding that dull softer simulants like cubic zirconia over time. Stylist's take: marquise points read more vintage and intentional than a round solitaire, so this piece layers cleanly beneath a shorter choker or stands alone in an open collar. The rhodium-plated 925 sterling silver keeps the whole necklace bright-white and hypoallergenic, while the adjustable 45–50cm chain lets you set it high on the collarbone or drop it toward the décolletage. The spring-ring clasp holds the pendant centered through a full day of wear, and the pavé accents on the bail catch light from a second angle for extra fire. Specs: marquise-cut moissanite, 11.5mm x 5mm (approx. 0.5ct DEW) - DEF color, VVS clarity, RI 2.65, 9.25 Mohs - pavé accent bail - rhodium-plated 925 sterling silver - adjustable 45–50cm cable chain - spring-ring clasp.
