From a find of fall in 2009, this is supposed to be the best example of a small pocket of davidite crystals from a locality near the famous ruby mines of Prislep. I saw only a few small examples at the Munich 2009 show, and then this 200-gram monster as well. It has super sharp faces for the species, and a remarkable chocolate-coloration which is not so ugly as they usually are. Impressive in person, I believe this ranks highly in aesthetics and import for this REE species.
