Benitoite crystals on Natrolite

Stunning specimen featuring Benitoite crystals on Natrolite with black Neptunites!

Five Benitoites of various sizes cover the snowy-white Natrolite and all are complete with a good bit of gem material in the tips! The surfaces are satiny to smooth with a soft rolling luster and beautiful Benitoite-blue color. One of the better small miniatures I've seen in a while!
From the Dallas Gem Mine, New Idria District, Diablo Range, San Benito Co., California.
Measures 3 cm by 3.9 cm by 2.4 cm in total size.
