I love Stones 💚
Especially the Green ones, called Emerald!
About this beautiful gemstone:
Emerald is a gemstone and a variety of the mineral
beryl colored green by trace amounts of chromium or sometimes vanadium.
Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are
highly included, so their toughness is classified as generally poor.
Emerald is a cyclosilicate.
