MOISSANITE
Moissanite: Natural Mineral, Lab-Created Gem & Properties
Moissanite is silicon carbide, a material known for strong brilliance and dispersion. Natural moissanite is extremely rare and was first identified in meteorite material; most moissanite sold for jewelry today is laboratory-grown. It is a distinct gem material, not diamond.

Origin and Formation
Natural moissanite occurs in very small quantities in certain meteorites and unusual geological settings. Commercial gem moissanite is manufactured under controlled conditions because natural crystals are too rare to supply the jewelry market.
Appearance and Properties
Moissanite has Mohs hardness around 9.25 and a high refractive index, producing vivid brilliance and rainbow flashes. It is generally durable for jewelry, though appearance differs from diamond, including stronger dispersion and characteristic optical behavior.
Identification and Collecting
Gemologists can distinguish moissanite from diamond with suitable instruments; a simple home test may be unreliable. Ask for clear disclosure of laboratory-grown origin and do not assume that diamond-like appearance means diamond identity.
Care and Handling
Moissanite can generally be cleaned with mild soap, lukewarm water, and a soft brush. Avoid harsh impacts and inspect settings periodically. Store separately from other jewelry to prevent damage to softer materials.
Frequently Asked Questions
Is this material a natural mineral?
Origin varies by material. Some are natural minerals or biological products, while most jewelry moissanite is laboratory-grown. Accurate labeling and documentation are important.
Can appearance alone establish authenticity?
No. Expert examination and reliable provenance may be needed, especially for rare materials and trade names.
