Datolite (var Botryolite) with Axinite-(Mn) (ex Pat Gross and Rich Kosnar Collections)

Item Description

This pair of specimens came originally from the noted collection of New Jersey collector, Pat Gross. The pieces are identified as being "Botryolite", which is a botryoidal variety of Datolite. Each specime hosts a few micro whitish "balls" of "Botryolite" which are sitting on small, bright yellow, bladed crystals of Axinite-(Mn). These are the only pieces of this material that I have handled, and would certainly make a great addition to any micro collection, or a suite of minerals from Franklin. Both pieces are accompanied by Pat Gross's hand-written collection box, which states that the "Botryolite" was identified by D. K. Cook. The specimens came to Rich Kosnar in the early 1990s.
