This specimen of natrolite and crossite is host to several crystals of benitoite to 1.7 cm across and a few crystals of neptunite. A few of the crystals have a considerable amount of gem rough. The top crystal has a particularly large cutter in it. I am setting the reserve bid at approximately 1/2 the gem rough value in this specimen. http://auction3.mineral-auctions.com/item.php?itemID=57
