A mesmerizing specimen of gemmy blue benitoite crystals with neptunite and natrolite from the famous Dallas Gem Mine, San Benito Co., California, USA. It comes from the collection of Stephen J. Gerome, MA, USA, no label. This fine combo piece features benitoite crystals to 8mm with matt to lustrous faces and translucent to gem areas. The blue color is rich. Black and lustrous, prismatic neptunite crystals to 15mm grow on the base. The snow white natrolite gives a strong contrast. In excellent condition – some outside edge contacts. With acrylic base – not glued.

Outstanding!
