A very large 3.5 cm doubly terminated realgar crystal sits perfectly centered on a matrix made of stibnite and calcite. The specimen is a floater and perfectly crystalized on all sides. Oliver had bought the entire pocket of these wonderful realgar specimens when they came out, and he had kept this amazing miniature specimen in his private collection for good reasons. It is super aesthetic and one of the very best pieces from the find. Certainly it needs protection from the light, as all realgar pieces do.
