2.
The chromium rich garnet uvarovite forms in interbeded layers with chromitite.
3.
The garnets make up two solid solution series : pyrope-almandine-spessartine and uvarovite-grossular-andradite.
4.
Uvarovite is one of the rarest of the garnet group minerals, and is the only consistently green garnet species, with an emerald-green color.
5.
The different species are pyrope, almandine, spessartine, grossular ( varieties of which are hessonite or cinnamon-stone and tsavorite ), uvarovite and andradite.
6.
The ugrandite garnets have Ca 2 + in the X position : uvarovite ( Ca 3 Cr 2 ( SiO 4 ) 3 ), grossular ( Ca 3 Al 2 ( SiO 4 ) 3 ) and andradite ( Ca 3 Fe 2 ( SiO 4 ) 3 ).
