Ulexite (TV rock)

Item Description

An uncommon hydrated borate, Ulexite 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!
