***Bringing you the very finest minerals ebay has to offer!!***


Native Silver & Gold with Acanthite

Silver City District (Carson District), Owyhee Co., Idaho

8.5cm x 7.67cm x 6.72cm

Ex. George B. Robbe (1884-1963)

Ex. A. E. Seaman Mineral Museum No. GBR-1388


Description/Interesting Notes:

A unique old time example of native silver from Idaho!!! This specimen retains an old Museum label noting its description of "Gold & Silver" however, while the siver is abundant throughout, the native gold is present only as minute portions visible only with close inspection - which makes me wonder if the material is possibly electrum (a gold & silver mixture) due to its unique yellowish hue!!! Regardless, it is an incredible specimen even if it were just native silver!!! This specimen hosts a complex group of acanthite crystals that are partially replaced by native silver (with gold?)!!! These crystals are all squeezed into recesses in the crytalline matrix, resulting in all manner of complex, angular features throughout!!! There are also other sulphide species in association as well, like some pyrite and possibly other species in minor proportions!!! There is a LOT going on with this rare and rich old timer and the pics don't even come close to doing it justice!!! This specimen retains an old lable from the Seaman Museum along with Robbe collection notation!!! Must be seen in person to be fully appreciated!!!
