Also know, what minerals is Emerald made of?

Emerald is a gemstone and a variety of the mineral beryl (Be₃Al₂(SiO₃)₆) colored green by trace amounts of chromium and sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor.

Furthermore, why is an emerald a mineral? The Mineral emerald. Emerald is the green variety of Beryl, and its most precious and valuable variety. Its intense green color has given it status as an important gemstone throughout the centuries. The deep color of Emerald is caused by traces of the element chromium, but sometimes also vanadium.

Emeralds are made from 4 elements that are found deep in the Earth's crust: beryllium, aluminum, silicon, and oxygen. These elements are found flowing in veins filled with hot water called hydrothermal veins. When the conditions are just right in these veins and the cool down, the emerald crystals start to form.
