Ferroan Turquoise var. Henwoodite

ID: CC264
An incredibly rich example of Henwoodite, a rare mineral variety of Turquoise, with green to blue botryoidal crusts almost completely investing a black ferruginous matrix. Henwoodite is very rare and this is probably the best example we have ever had. The individual spherules measure less than 1 mm diameter but hundreds coat the surface of the matrix. Henwoodite is an iron-rich (ferrian) variety of Turquoise similar to Rashleighite. The specimen is accompanied with a Col. Williams label, whose mineral collection was originally sold in the early 1990s.
