A superb rarity in unusually large and rich form...this is a very rare crystallized example from Texas of Calomel on matrix. This specimen probably should be trimmed in half to maximize value, and i'll do it if it doesnt sell since each half will be worth the same as the whole, with superb pockets of the large calomels! Edgar Bailey was a noted mineralogist and field collector of Terlingua minerals, and the species Edgarbaileyite is named after him in honor. This is from his collection and was self-collected by him, part of a suite of such pieces. (not from Feinglos coll.)
