Item #17068 Silver, Arsenides 15.0x8.3x1.4 cm Largest Crystal Size: n/a $120.00 Silverfields Mine Cobalt Ontario, Canada A very nice specimen that is both mineralogical and geological in nature.

Item #27093 Silver, Arsenides 14.2x7.7x0.8 cm Largest Crystal Size: n/a $140.00 O'Brien Mine Cobalt Ontario, Canada Here is an interesting mineralogical texture! This vein of very dark carbonates, possibly fine-arsenide tinted, hosts silver in fine dedritic form and some re-mobilized into fine veinlets. Some of the silver appears sheared. The dendritic silver is coated by an undetermined arsenide mineral. Rich and interesting! Collected in 1917!
