This is a major cabinet specimen worthy of any fine collection, quite a level above the usual sort of sulfur you see (of which even small ones of superb color are now going for five figures). The crystals are so sharp they could be carved, and the color is LEMON yellow. Old piece, from the collection of a longtime customer of the great Italian dealership Ennio Prato, sold to me by his son Riccardo. The photos say it all! Joe Budd photos.
