An unusual specimen with blocky, blue-included anglesite crystals from an abberant pocket found in the early 1980s. The cause of the color is unknown so far as I am told. The piece has some small areas of damage but much of the front face is nevertheless in good shape. I have this piece and one other from one larger one I had trimmed, and otherwise have only seen one other for sale before. Unusual material, to be sure! 6 x 4.5 x 4.2 cm
