This RAZOR-sharp, pristine, totally gemmy fluorite crystal measures 2.5 cm across its longest edge, more through the diagonal. It is absolutely riveting, and disappears on white, it is so clear (except for the minute iron staining on the underside of the piece). This is characteristic of the 1980s production we fondly miss, and referred to as "ice cube fluorites." There are larger specimens, but not of any better quality or in such condition generally. So, for the size, this is a very special, superior quality miniature (as you'd expect from such a well-known fluorite collector!)
