description Enstatite Overview
Enstatite is a magnesium-rich orthopyroxene, a pyroxene-group silicate found in many mafic and ultramafic igneous rocks and in some meteorites. Its ideal composition is MgSiO3, although natural specimens commonly contain some iron, which changes their color and places them in the enstatite-ferrosilite series. Gem-quality material is usually brown, green, gray, or bronze and is used for collector specimens, faceted stones, and occasional cat's-eye cabochons.
help Enstatite FAQ
What is enstatite made of?
Enstatite is a magnesium-rich orthopyroxene with an ideal composition of MgSiO3. Natural material commonly contains some iron, which can change its color and mineral classification.
Where is enstatite found?
Enstatite occurs in mafic and ultramafic igneous rocks, including rocks rich in magnesium and iron. It is also found in some meteorites, making it important in both Earth and planetary geology.
What colors can enstatite gemstones have?
Magnesium-rich enstatite is often pale green, gray, brown, or colorless, while added iron can deepen the color. The exact appearance depends on chemistry, transparency, and the quality of the individual specimen.
Is enstatite commonly used in jewelry?
Transparent enstatite can be cut as a collector gemstone, but it is less common in jewelry than quartz, garnet, or topaz. Its appeal usually comes from rarity and mineral interest rather than widespread commercial availability.
