PF7-AYFHessite : Ag2Te, Gold : Au

Botés, Alba Co., Romania

Dimensions: 2.1 cm x 1.7 cm x 1.5 cm

WOW! This is an incredible, world-class thumbnail of this very rare silver species! Such pieces are usually 100-200 years old and more. Pristine, aesthetic examples are few and far between in any size, but THIS ONE is a competition level piece for aesthetics, aside from the rarity and history. Note the Smithsonian label showing it is from the Carl Bosch collection. Bosch didnt collect anything bad. Even his small stuff is good, as this exemplifies! 2.1 x 1.7 x 1.5 cm
