Ulexite 'clamshell' ex Reynolds Coll.

Item Description

Aptly and uniquely shaped "clamshell" ulexite from the famous U.S. Borax open pit mine. The shimmering acicular crystals resemble a clam shell, giving the piece its name. According to a quote from Rock Currier: "These were found in the mud/shale at the top of the tunnel near the big portal to the Boron underground mine that opened into the bottom of the open pit (Rock Currier). These RARE and fantastic looking old-timers date to the 1960s. Acicular blocky ulexite, when cut and polished perpendicular to the long axis of the crystals is known as TV rock, for its fiber optic effect. Ex Bob Reynolds Collection. These fascinating old-timers are RARELY on the market today, and only some few were kept by mostly local collectors at the time.
