Gem Mine, San Benito County, California, U.S.A.
This thumbnail specimen consists of a small piece of dull, gray host rock on which rests a single tabular Benitoite. This crystal measures 0.4" (1.0 cm) in diameter and is in very good condition, showing no fresh damage. Its trigonal tabular form is incomplete due to old damage and apparent weathering, but is still rather well-defined. Its color is a dull gray and its luster is dull and waxy- again, both are likely due to weathering. Under shortwave UV light, the crystal glows the standard bright blue, however. It is accompanied by 5 black neptunite prisms. The gray base rock has a substantial amount of glue attached to one side- I am not sure how one would remove it without threatening the integrity of the piece.
