Fluorite ("phantom" cube) on Muscovite (ex Dr. Stephen Smale Collection)

Item Description

A classic and a staple from the Yaogangxian Mine. The Fluorites from this locality are some of the most distinctive, eye-catching and highest quality examples from any Chinese locality. This particular piece hosts a beautiful, 2.2 cm, razor-sharp, highly lustrous, GEM quality, blue and purple "phantom" cube that is wonderfully isolated and aesthetically perched atop silvery Muscovite matrix. The Fluorite appears to be damage free to the naked eye, though when I looked closely with a loupe I could see a few VERY TINY imperfections. Overall, it's very difficult to obtain pieces of this quality with such excellent aesthetics and balance. The piece displays wonderfully and really stands out as a fine example from this famous mine. Valued at $1,750 in the inventory. Ex Dr. Steven Smale Collection. Along with amassing one of the finest private mineral collections in the world, Steve is a renowned mathematician.
