Jordanite is a rare lead, arsenic, antimony sulfosalt and this fine combination specimen is from the Type Locality - the Lengenbach Quarry in Switzerland. A 1.1 cm long aggregate of lustrous, lead-gray, prismatic jordanite crystals is beautifully adjacent to or near to gorgeous, gem, yellow-brown sphalerite crystals to 1.0 cm. These crystals are very attractively lined up on a sculptural matrix of classic, sparkly, sugary, layered, Lengenbach Quarry dolomite. The sphalerites are large for the Lengenbach Quarry. Ex. Mullane Collection. Old material.
