MOISSANITE (Synthetic)
Lab-Grown Moissanite: Properties, Diamond Comparison & Care
Lab-grown moissanite is silicon carbide manufactured for use as a diamond alternative. It has high hardness, strong brilliance, and pronounced dispersion. Although it can resemble diamond, it has different optical and physical properties and should be accurately described as laboratory-grown moissanite.

Origin and Formation
Commercial gem moissanite is grown using industrial crystal-growth methods because natural moissanite is exceedingly rare. Manufacturing allows crystals to be cut into consistent shapes and sizes for jewelry.
Appearance and Properties
Moissanite has Mohs hardness around 9.25 and often shows stronger rainbow-like dispersion than diamond. It is durable for many jewelry uses, but hardness alone does not make it indestructible. Optical properties and thermal behavior differ from diamond.
Identification and Collecting
A trained gemologist can identify moissanite using appropriate instruments. Lab-grown origin is part of the material description, not a defect; clear disclosure helps buyers understand what they are purchasing.
Care and Handling
Clean with mild soap, lukewarm water, and a soft brush. Protect the setting from impact and inspect prongs periodically. Store separately from softer stones and follow the jeweler’s advice if the stone has special settings or treatments.
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.
