Муассанит — Википедия (3 pages).pdf

Moissanite (SiC) is a rare natural mineral, primarily found in meteorites and corundum deposits. It's known for its diamond-like brilliance and hardness (8.5-9.5 Mohs). While natural crystals are tiny, synthetic moissanite is widely produced and used as a diamond simulant due to its similar optical and physical properties, though it exhibits stronger birefringence and thermochromism. It's also abundant in space, forming around carbon-rich stars.
