Faujasite - Sold

Faujasite is a zeolite mineral with cubic symmetry (Coombs et al. 1997). The name honors Barthelemy Faujas de Saint Fond (1741-1819), mineralogist and vulcanologist (Damour, 1842). Most crystals are octahedral, like those on this sample, many are coated with accessory phillipsite. The matrix is vesicular basalt; each gas pocket in the matrix contains a different surprise. This specimen was part of the personal collection of Ralph Merrill, proprietor of the prolific mail order business Minerals Unlimited, obtained in 1956. Merrill's collection card and label, as well as an old German script label form the Schenieder collection, also ship with the specimen.
