Name:
Named for the Monteneve Mine, Italy, the type locality.
Fourth Sb-rich garnet member after members of the bitikleite group: bitikleite, dzhuluite, and usturite. The first "fully antimonian" member regarding the B site occupancy and first member with essential ferrous iron at the T site. A fully non-silicate, ferrate garnet. Sb2-Fe3+Fe2+-analogue of dzhuluite and usturite.
