An intrepid mineral buyer who stalks fine specimens in some of the most remote places of the world brought this VERY RARE spinel-twinned fluorite crystal home about five years ago; he said he buys every one of these he sees, and that’s not many. It is a complete, TRANSPARENT pink crystal, flat and lustrous on the two side faces so that you can see right through it. From the side, you can clearly see the twinning re-entrant. There is a small bit of edge wear alon gthe top only, otherwise its in good shape. Note the interesting (and to my experience , unique) epitaxial growth of two flat, colorless fluorite crystals on the face as well! 8.5 x 5.4 x 2.2 cm
