Herderite (unique 34-xl set) ex Robert Whitmore Coll.

Item Description

A remarkable and huge collection of 34, glassy and lustrous, hydroxylherderite crystals from this classic locality, found over 40 years ago! Hydroxylherderite crystals of such size, from any US locality (or any locality outside of Brazil for that matter) are extremely rare. This is a significant US species collection, way beyond the norm of any reasonable expectation. The glass-covered display case measures 33.0 x 25.3 x 2.2 cm. Collected by Hollman and Esther Whitney in 1962-63. to me, Ex. Robert Whitmore Collection. Valued at $1500. although esoteric, this is a MAJOR and unique assemblage, and perhaps important for study
