Spangolite with Quartz
Blanchard Mine, Bingham, Hansonburg District, Socorro County
6.6 x 4.6 3.3 CM (cabinet)
Bright, vivid blue-green crystals of Spangolite contrast with a drusy Quartz block. The Spangolite is prominent and presents well on the matrix. A choice older specimen of this colorful and rather uncommon Copper mineral not often seen as non-micromount display specimens. Crystals are easily visible with naked eye, this is an attractive display example from Bingham. Older labels included from several collections, among these are Danilo Rolando, Ch Dubois and Sandro Maggia.
Unusual flower-like group of radiating crystals which are about half Pyromorphite (yellow) and half Plumbogummite (powder blue). The pseudomorphing is roughly frozen in the middle of the process. Seen on one side the crystals all look like yellow Pyro and on the other side the blue color is dominant. The radial arrangement of the crystals makes this a nice esthetic miniature and a fine example of this classic pseudomorphing. The Plumbogummite of Yangshao Mine/ Daoping are widely considered to be be the best ever found in the world.
A somewhat sharp complete single cube of the rare earth specie Lueshite from the type locality. This Sodium-Niobium mineral is not often available, the metallic black to silvery color is typical of crystals from here, and the size is above average. This crystal has rough spots on some edges as seen but is overall in good shape, a nice crystal of this rare specie.
