S18236 – Cuprite

An unusual specimen of copper after cuprite of preferential replacement, in conjunction with a single non-pseudomorphed cuprite. This kind of specimen is fairly uncommon from Bisbee. A thumbnail, such as this one, is distinctly different and in mint condition.
S16345 – Copper

An extremely good Bisbee pseudomorph from the 1000 level of the Cole shaft. This is an exceptionally sharp, incredibly well articulated and balanced copper after cubic cuprite. Ex. Bill McBride collection
