Colemanite - $20 West Dump, U.S. Borax Open Pit, Boron, Kramer District, Kern County, California Small cabinet - 8.2 x 6.2 x 4.8 cm (3.2 x 2.4 x 1.9 inches) 188 grams (0.41 pounds) Ex Carol and Ed Headley collection Specimen status: Available Send an email with specimen number to order A grayish matrix - presumably solid
(or nearly so) colemanite is decorated on several faces
with carpets of semilustrous, light grey, translucent
colemanite crystal blades, most of which are terminated.
Individual crystals reach about 5 mm, and most are
complete. Has several nice display angles which do not
require a stand. Overall condition is quite nice.
Accompanying collection label indicates the specimen was
collected in September of 1990. Material of this nature
was at one time fairly common on the mineral market -
especially here in Southern California - but with the
locality being closed to collecting for some years,
these specimens - especially those of quality - have
become more scarce.
