   Grossular ,or grossularite, is a pale green, pink, brown, or black garnet, Ca3Al2(SiO4)3,occurring  alone or as a constituent of the common garnet.Grossular (also known as ), like other  garnets,forms rounded crystals with 12 rhombic or 24 trapezoidal faces or combinations of  these and some other forms. This crystal habit is classic for the garnet minerals.  Grossular is the calcium aluminum garnet and forms in contact or regional metamorphic  enviroments as does andradite the calcium iron garnet.It is believed that these garnets  form from the metamorphism of impure siliceous limestones.Grossular has many color  possibilities and is probably the most colorful of the garnets.The orange variety is the  most common and specimens of orange grossular crusts are prized by many collectors. Green  variety is called tsavorite and is occassionally cut as a gem.
