Description

You are bidding on an extremely rare sample of loseyite and part of the holotype material! Most samples of loseyite are absent of the mineral and legitimate samples are very hard to obtain. This is a sample from the former Vandall King, L.C. Weyman and Harvard collections! The sample has a bladed cluster of tabular, white loseyite crystals on a pyrochroite, chlorophoenicite and sussexite matrix. One of the rarest Franklin species.
