Ulexite (TV rock)

Item Description

Ulexite, a hydrated borate, is one of the rare beautiful, oddball species that were found at the borate deposits in California. It is also called "TV rock" for its unusual fiber-optic-like optical properties. This solid vein specimen of prismatic crystals has high luster and a pearlescent, white color. The ends are contact terminations from coming into contact with the pocket walls. Very fine for the spcies and very rare as a specimen, instead of simply as cleavage masses!
