Moissanite is a brilliant gemstone made from silicon carbide. It was first discovered in a meteorite crater and is now recreated in labs, offering an ethical and dazzling alternative to diamonds.

No — moissanite is a distinct gemstone with its own brilliance and fire. While it resembles a diamond, moissanite has a higher refractive index and often outshines a diamond's sparkle.

Moissanite is a more affordable, ethical, and eco-friendly option than diamonds.

• Brilliance — moissanite's refractive index (2.65–2.69) is higher than a diamond's (2.42), creating more rainbow-like flashes of light.
• Hardness — moissanite scores 9.25 on the Mohs scale, just below diamond's 10, making it highly durable for everyday wear.
• Value — moissanite typically costs a fraction of a comparable diamond.

Moissanite is grown from silicon carbide using a thermal growing process, with each stone crafted specifically as a gemstone. Lab-grown diamonds are created from pure carbon using HPHT (High Pressure, High Temperature) or CVD (Chemical Vapor Deposition) methods that replicate natural diamond formation.

Yes — moissanite will often read as a diamond on standard testers due to its thermal conductivity. Specialised testers can distinguish between the two.

Moissanite is 100% conflict-free and requires no mining, giving it a smaller environmental footprint than diamonds — which are often linked to unethical mining practices and environmental damage.
