The other name, idocrase, is from the greek and means mixed form, an allusion to its crystals showing a mixture of other mineral forms. The crystals belong to the tetragonal symmetry class and show a square cross-section perpendicular to the long axis. Tetragonal crystals are uncommon and vesuvianite fortunately produces some very nicely shaped crystals.Oddly enough, some of its structure is similar to that of grossularite, a garnet, which is an isometric mineral. Its structure is also interesting in that it is composed of both SiO4 groups and Si2O7 groups. Vesuvianite could be classified as a nesosilicates because of the SiO4 groups, but the higher organization of the Si2O7 groups puts it in the sorosilicate subclass.Vesuvianite forms as a result of contact metamorphism on impure limestones and is usually found with other exotic minerals. A massive green gem variety is called californite from where it is found. It is a somewhat rare and beautiful mineral that can rival many other minerals for interest among mineral collectors.
