Pyrolusite (rare CA locale) ex Trimingham Coll.

Item Description

Mineral specimens of any variety are RARE from this former iron mine. Splendent, sharp, metallic-gray pyrolusite microcrystals fill the sculptural vug lined with botryoidal pyrolusite on massive hematite matrix on this rare large combination piece from the Bob Trimingham Collection. A must for the locality or species collector, and not like any I have had before. The Trimingham collection was rich with such rare California material.
