Emerald belongs to the Beryl group (Mohs hardness 7.5-8) and, like most Beryls, has a hexagonal crystal structure. It owes its green color to chromium ions that are embedded in the crystal lattice. The most beautiful Emeralds come from Colombia, as the crystals here have grown in cavities, while in other locations (Brazil, Pakistan, Russia, Austria, etc.) they are found surrounded by matrix rock.
