A cabinet sized, twinned, blue Fluorite crystal with purple edges on Feldspar with minor Muscovite. It has a candy-like luster and a complex surface texture from formation. These twins are notoriously mis-represented as Spinel Law Twins when they are in fact Contact Twins. Larger ones have become highly sought after by collectors, especially when they have color.
 
Measurements: 10.9 x 8.7 x 3.6 cm.
