.42" Raspberry, Grossular Garnet in Matrix - Coahuila, Mexico

The colors that grossular garnets typically display range from yellow, green, brown and in some cases a pale-pink color, with deeper-red colors being extremely rare. However, in the late 90's, raspberry-red garnets were discovered at a locality known as Sierra de Cruces, Coahuila, Mexico. This color had previously never been documented in natural grossular garnets. These garnets are also frequently sold under the name Rosolite.

There are many species of garnet which include pyrope, almandine, spessartine, uvarovite, andradite and grossular (varieties of which are hessonite, cinnamon-stone and tsavorite).
