Fairfieldite (rare, large crystal groups)

Item Description

This piece is from the famed Foote Mine in North Carolina, which has produced some iconic phosphate specimens over the years. One of the most well-known phosphates from this mine is Fairfieldite, a rare hydrated calcium manganese phosphate species, that is typically seen in smaller crystals (measuring in mm, not cm). The largest Fairfieldite group on this piece measures a whopping 2.0 cm, which is quite large for the species, and not just from the Foote Mine, but anywhere. A really cool example of this elusive and desirable material, with arguably the largest crystal aggregates we've had to offer from the locality. Valued $1,500.
From the collection Jack Eaker (whose label says the specimen was identified by Jason Smith).
