This botryoidal specimen exhibits the finest, "Kelly blue" color, luster, and translucence, to be found from this venerable old mine. Specimens of this quality and color are increasingly rare in dealer stocks. Much of it eventually drifts over to lapidary use, as the carving value of pieces like this with the best color and thick rind probably exceeds the specimen value. This one really is THAT good...luster and color are very important in grading these, and I have seen a LOT of them.
