Green grossular garnet crystals of fine form and clarity have been found recently in Tanzania, at the Karo pit of the tanzanite mining belt. Although the crystals tend to be relatively light in color, they are consistent in gemological properties and composition with the grossular variety popularly known as tsavorite. The very distinct and complex morphology of these crystals is remarkable. Eight different crystallographic forms have been identified, including one that has never before been recognized for any member of the garnet group.
