A magnificent mass of platy Acanthite and Acanthite crystals lightly dusted with microcrystalline Pyrite, all enveloping a matrix of massive and crystallised Quartz. From Banská Štiavnica in the Banská Bystrica Region of Slovakia, the Acanthite forms 1 to 2 mm equant crystals that richly cover a film of micro-crystalline Pyrite. The Pyrite coats large Acanthite plates measuring up to 5 cm long, but of irregular shape. A 2 cm long, crude and slightly milky quartz crystal sits amongst the Acanthite on the top surface. A very rich example of Acanthite from Banská Štiavnica with a lot of well-formed crystals. The specimen is accompanied with very fragile old handwritten label, protected by a mount of thin card within a protective translucent envelope.
