Beryl, the mineral of which emerald is a variety, has a chemical composition of Be 3 Al 2 (SiO 3) 6. When pure, beryl is colorless and known as goshenite.. Trace amounts of chromium or vanadium in the mineral cause it to develop a green color.
Associated minerals in these deposits are dolomite, pyrite, calcite, quartz and albite. Because of emerald's relatively high hardness and specific gravity, it is sometimes found in eluvial and aluvial deposits. Emerald is usually recognized by its color, form, hardness and specific gravity.
