Silver ore with Smaltite

Item Description

A visually striking, rich and rare, old-time combination silver ore specimen from Cobalt. Striking, dendritic, spinel-twin silver crystal clusters are all rimmed by silvery-bright smaltite on this outstanding sliced specimen. The intricate patterns are surreal and look life ferns. Smaltite is the arsenic-deficient variety of skutterudite and is quite uncommon worldwide. The isolation and sculptural quality of the crystals, to 4.6 cm, is exceptional in the contrasting quartz matrix. Crystallized silver and smaltite specimens are extremely rare from any worldwide locality and this is a fine, very rich old-time example. 43 grams.
