Benitoite, Natrolite, Neptunite, Joaquinite, California State Gem Mine, San Benito Co, CA, USA
Unknown Owner
A heck of a combination specimen. This piece features several species including benitoite, natrolite, neptunite, joaquinite, and even what I think is a very small diopside! A Willard Perkins piece with his famous typed labels on the top of the Styrofoam in the box.
