Moissanite FAQ

Moissanite is a real gemstone composed of silicon and carbon (chemical formula SiC). Henri Moissan discovered minute crystals of this mineral in a meteor crater in 1893; however, natural moissanite is too rare for jewellery, so today's moissanite is lab-grown.

Moissanite's popularity comes from a blend of advantages:

• Brilliant fire and sparkle, its refractive index (2.65–2.69) creates rainbow flashes that can outshine a diamond. • Exceptional durability, a hardness of 9.25 on the Mohs scale makes moissanite one of the hardest gemstones, second only to diamond. • Ethical & sustainable, lab growth avoids land disruption, water consumption, and conflict concerns linked to diamond mining. • Affordable luxury, moissanite offers high-end sparkle at a more accessible price.

No. Although moissanite looks similar to diamond, the two gems differ. Moissanite is silicon carbide; diamond is pure carbon. To the naked eye, high-quality moissanite appears nearly identical to a diamond, but they have distinct optical and physical properties.

Yes. Moissanite ranks 9.25 on the Mohs hardness scale, making it less prone to chipping and breaking. With proper care, moissanite engagement rings, wedding bands, and other jewellery will retain their brilliance and resist abrasions for decades.

Sparkle depends on a gemstone's refractive index, its ability to bend light. Moissanite's refractive index of 2.65–2.69 surpasses diamond's 2.42. This means moissanite rings and earrings will always deliver eye-catching brilliance, especially in mixed lighting.

No. Moissanite is highly resistant to cloudiness because its crystal structure lacks internal oils or coatings. It withstands heat and daily wear without becoming hazy. With regular gentle cleaning, it retains its clarity indefinitely.

Yes. Lab-grown moissanite avoids the environmental damage and human rights issues often linked to diamond mining. Diamond extraction can destroy ecosystems, cause deforestation, and consume large amounts of water and energy. Because it is created in a lab rather than mined, moissanite is conflict-free. Moissanite's lab origin means transparent supply chains and a clear conscience.

Shoppers choose moissanite for several reasons:

• Brilliance & fire, its high refractive index creates dazzling sparkle. • Durability, 9.25 Mohs hardness and no cleavage plane make it strong for everyday wear. • Ethical peace of mind, lab-grown origins eliminate conflict and reduce environmental impact. • Affordability, moissanite offers a diamond-like appearance at a fraction of the cost.

Choosing moissanite isn't about replacing diamonds; it's about selecting a gemstone that matches your values, budget, and aesthetic.

• Clean regularly, use warm water, mild dish soap, and a soft brush to remove oils and dirt. • Store separately, keep moissanite pieces away from harder stones and rough surfaces to avoid scratches. • Avoid harsh chemicals, remove jewellery when using household cleaners or applying lotions to maintain lustre.

With proper care, moissanite retains its brilliance and sparkle for generations.
