A fascinating specimen of slightly gemmy blue benitoite crystals with neptunite and natrolite from the famous Dallas Gem Mine, San Benito Co., California, USA. This combo piece features benitoite crystals to 6mm with matt to lustrous faces and translucent to gemmy areas. The blue color is rich. Black and lustrous, prismatic neptunite crystals to 6mm grow on the base. The snow white natrolite base gives a strong contrast. Some damages.

Wonderful!
