A very rich and showy Tsumeb copper ore specimen. A sparkly druse of deep wine-red cuprite microcrystals coats a mounded, vuggy, 3-dimensional matrix of brecciated, massive cuprite nicely complimented by small calcite crystals on both sides. The cuprite is darker than the photo shows, as the lighting and high luster of the cuprite brightened the piece. Hefty for its size! Ex. Rob Smith Collection and a highly representative Tsumeb cuprite specimen.
