Rubellite from
Black Mountain Quarry (Black Mountain pegmatite), Rumford, Oxford Co., Maine, USA

Locality type:Quarry
Classification
Species:Tourmaline var: Rubellite
Formula:A(D3)G6(T6O18)(BO3)3X3Z
Comments:Black Mountain Mine is noted for its "fans" of pink elbaite - some as large as perhaps a foot high and across. The material is largely non-gem quality to "representative" quality. Really good quality crystals are quite rare here. It is the size and aesthetics of the "fans" which have attracted collector attention to the locality over the years.
Quality for species:Good crystals or rich for species - important (!)
Confirmation
Validity:Confirmed
Confirmation Methods:Wet Chemical
