This important benitoite is, at least, one of the largest, complete crystals ever found for the species! It is complete all around and has good form, given that larger crystals tend to be distorted. It is included, and so opaque. It was mined in 1969, went to Bill Larson, and then to John Sinkankas where it stayed for many decades. Its not gemmy by a long shot due to heavy inclusions of glaucophane (so says John). But, it is complete, and shocking in size once you realize what you are looking at! I am told there are several others of comparable siz ein existence, but I have not seen any such for sale, nor any myself in collections.
