11.8 x 11.0 x 5.0 cm. This is a dramatic and sculptural specimen of bright, hackly, moderately iridescent silver crystals partially encased in a quartz vein. It is very aesthetically attached to the mounded, silver ore-basalt cabinet matrix. Accenting the piece are a few scattered black blebs of native bismuth. Ex. John Durkos (acquired from the ...

8.7 x 6.0 x 1.4 cm. Allargentum is a metalloid alloy of silver and antimony. It is rare worldwide. The finest examples come from the famous silver mines at Cobalt, the historic old mines in Germany and from recent finds in Morocco. This is a solid narrow ore vein of matte-gray and lustrous, bronzy, scalloped allargentum. Not pretty to look at, but ...

Silver dendrites, very rich in the calcite-rich metasediment wallrock of a wide carbonate vein (dolomite core barren faintly pinkish calcite selvage) with a narrow massive grey tetrahedrite (XRD) vein at the calcite-wallrock boundary. Collected by Doug Scott in October 1963 underground from the back of the long drift below Glen Lake Mine. Doug ...
