Artinite Pit, San Benito County, California, U.S.A.
A crust made up of several intergrown Artinite clusters comprises this specimen. These clusters do note exceed 0.8" (2.0 cm) in diameter and are generally in good condition, though the largest one is considerably damaged. Each cluster contains scores or perhaps hundreds of compact, fibrous radiating Artinite needles that reach lengths of 0.4" (1.0 cm). They are too small and intergrown to study as individuals, but likely have relatively good monoclinic form. The clusters have a white color and a generally dull luster, and are dimly translucent. Where the interior of a cluster is exposed, the crystals show a much brighter, pearly luster. Only a few very thin crusts of what appear to be serpentine serve as a base for the Artinite crust.
