A velvety, botryoidal crust of black goethite is the matrix for five intergrown spheres of lustrous and translucent, essentially colorless smithsonite, to 1.8 cm across. The smithsoite is the smoothest, most lustrous and bubbly smithsonite of this style I can recall seeing, and is really just gorgeous in person, despite the fact that normally it is hard to rave about a colorless smithsonite?! There is a faint grayish color imparted to the smithsonite by the underlying goethite. For color and textural contrasts, this specimen is spectacular!
