A very rich, sizable specimen of the uncommon Copper Sulfate Spangolite from the famed Blanchard Mine. The Spangolite is covering a quite large area with a few small zones of Brochantite crystals. The mineralized zone on this piece is much larger than the usual tiny patches. This piece has substantial areas of sparkling blue Spangolite with hundreds of tiny, gem clear crystals. The hard rock matrix gives a nice jagged contrast to the mineralized faces. Ex John Buckley collection, this is a far, far better than typical specimen from this classic and well-respected locality. This is one of the very few pieces that looks fine on a display shelf and also amazing under a microscope.
Spangolite with Brochantite, Barite etc
Blanchard Mine, Bingham, Hansonburg District, Socorro County
8.2 x 6.3 x 2.7 CM (cabinet)
A complex specimen with a mix of bright blue Spangolite crystals in several patches mixed with Brochantites. The Spangolites are sharp and gemmy under good magnification, the matrix is quite colorful and more rich than typical from this great USA locality. Typically Spangolite is a micro mineral in most collections, this has enough good coverage to be visible by naked eye but certainly far more beautiful under magnification.
