This is a very fine, sparkling large-miniature-sized specimen of this classic old Bolivian material to have survived intact for decades. It would have come out of the Siglo Veinte Mine (20th Century Mine) in 1981 from a remarkable discovery regarded best of species by many for the size and beauty of these sparkling crystal plates. They have long since disappeared into collections and only come to market generationally, particularly in this quality. This is a lovely, shimmering plate of solid vauxite, composed of hundreds of small, scintillating, translucent, rich blue crystals, and they are unique in this style to this find and place and almost unheard of from other locations. It has a nice aesthetic, undulating surface as well. An excellent miniature example of this extreme rarity from a best of species find. Ex. Paul Stahl collection.
