Emerald

Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium or sometimes vanadium. Beryl has a hardness of 7. 5–8 on the Mohs scale.

Most emeralds have many inclusions, so their toughness is classified as poor.
Emerald is a cyclosilicate.
It occurs mainly in association with quartz, muscovite, albite, schorl, microcline, fluorite, smoky quartz and elbaite.
