Description

You are bidding on one of the finest examples of this species I have ever seen, and I have collected minerals from the Foote Mine for over 20 years. A very large vug on matrix hosts hundreds of perfect tabular, twinned crystals of brannockite as singles and clusters up to 3mm. There are also sprays of bavenite and nice albite crystals present. A truly world-class example of the species from the type locality. Also has really nice blue fluorescence in SWUV.
