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.

Graduated Moissanite Tennis Necklace | DEF VVS Silver

About This Product

A red-carpet riviere reimagined in brilliant moissanite, this graduated tennis necklace draws a single unbroken line of round-brilliant stones around the throat. The stones swell from delicate accents at the clasp to a bold center cluster at the base, so light pools precisely where the eye settles and the neckline gets a built-in focal point. Every stone is four-prong set in 925 sterling silver finished with bright 18K white gold plating, lifting each gem high to catch the light from any angle rather than burying it in metal. Moissanite carries a 2.65 refractive index against a diamond's 2.42, so the graduated line throws noticeably more fire — a living, prismatic flash with every turn of the head. The gems are DEF colorless and VVS clarity, ranking 9.25 on the Mohs scale for everyday durability that resists scratching and clouding. A heart-tag extender chain lets you size the drape from a snug throat-hugging fit to a looser collar, so it layers cleanly under an open collar or sits solo above a strapless neckline. Expert take: a graduated tennis line is the most flattering of the riviere styles because the tapering stones echo the natural slope of the collarbone — wear it as the single statement piece with studs and let the necklace carry the look. It moves comfortably from a wedding or party to the office desk to an evening out. Specs: round-brilliant moissanite, DEF color, VVS clarity, refractive index 2.65, 9.25 Mohs; graduated center stones near 1.0ct DEW (about 6.5mm); four-prong setting; 925 sterling silver with 18K white gold plating; adjustable extender with heart charm.
