Emerald is a gemstone and a variety of the mineral beryl coloured green by trace amounts of chromium and sometimes vanadium. Beryl has a hardness of 7.5–8 on the MOHs scale. Most emeralds are included, so their toughness (resistance to breakage) can be classified as poor. However, hydrothermal (HD) emeralds are less included and therefore have better resistance to breakage, they are also much cheaper than mined emeralds. Hydrothermal emeralds are often referred to as "created", as their chemical and gemological composition as well as appearance is the same as their natural counterparts but they are man-made.
