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.

Heart-Cut Moissanite Open Heart Pendant Necklace

About This Product

A love letter you can wear, this open-heart pendant frames a 6.0mm (0.8ct DEW) heart-cut moissanite prong-set at the lower point of a polished open-heart silhouette, with a short row of pavé stones tracing the upper right curve. The heart cut is faceted to throw light in every direction, and moissanite's 2.65 refractive index (versus 2.42 for diamond) gives it noticeably more fire, so the center reads brilliant even under soft indoor light. Ranked 9.25 on the Mohs scale, it resists scratching and stays crisp through daily wear. The stones are DEF colorless and VVS clarity, so the sparkle stays clean and icy rather than tinted. The frame and chain come in your choice of 18K white gold or 18K yellow gold plating over 925 sterling silver, with a delicate cable chain included. Expert take: the open, negative-space heart keeps the pendant light and modern rather than sentimental-cute, so it layers beautifully with a longer chain or a chunkier statement piece and sits well against a crew neck or an open collar. Because the center stone floats inside the frame, it catches the eye without overwhelming a smaller frame, making it an easy everyday piece that still feels gift-worthy for an anniversary, birthday, or Valentine's Day. It arrives ready to wear straight from the box. Specs: 6.0mm (0.8ct DEW) heart-cut moissanite center, DEF color, VVS clarity, 9.25 Mohs, refractive index 2.65, pavé accent stones, 18K white or yellow gold over 925 sterling silver, cable chain included.
