Description

You are bidding on a small sample with both eakerite and brannockite on the same piece! In all my years collecting minerals from the Foote Mine this is only the second piece I've seen with both these type species together on one specimen. While neither is of great quality, the fact that they are together on this piece is what makes it so rare. The eakerite occurs as small colorless prisms, and the brannockite as very rich, sugary plates that fluoresce a strong blue in SWUV.
