Emerald is a gemstone known for its bright green color and is the birthstone for May. It also marks a couple’s 35th wedding anniversary.
Emerald is a member of the beryl family colored green by trace amounts of chromium and sometimes vanadium. Beryls have a hardness of 7.5-8 on the Mohs scale, but most emeralds are highly included so their toughness is classified as generally poor. Emerald is the rarest of all gemstones and so is valued accordingly. They are mined all over the world, primarily in Central & South America and Africa.
