Arsenopyrite with Quartz and Muscovite (ex Dr. Stephen Smale Collection)

Item Description

Here we have a lovely miniature display specimen featuring a 1.2 cm, sharp, well-formed, tapered, silvery-gray colored pseudo-orthorhombic (monoclinic) crystal of Arsenopyrite aesthetically perched atop a matrix of very gemmy prismatic Quartz crystals with a coating of beige colored Muscovite "rosese". The Arsenopyrite is complete on the top and the sides, though I can see a small contact near the base of the crystal. Very attractive in person, and certainly one of the better miniatures of this material that we've offered. Valued at $500. Ex Dr. Steven Smale Collection.
