Big Creek, Rush Creek deposit, Fresno Co., California
Ex. Steve Pullman
A fairly large specimen of Sanbornite which is off white in color. One side of the specimen is almost completely composed of cleavage planes of Sanbornite which exhibit a high, pearlescent luster when the light strikes the surfaces at the correct angle. There is also present white to gray colored massive Quartz and other unidentified, dark colored blebs some of which may be Traskite.
Flaws: Essentially massive material.
