Description

A very aesthetic twinned pair or large tarnowitzite crystals featuring a generous inclusion of native copper. The two exaggeratedly large crystals flare out towards their terminations which provides much extra surface area in just the right place.

The terminations are super lustrous and translucent to clear thus revealing the captured native element that appears on the surface as fine crystals with an aged patina and within the tarnowitzite as bright metallic pink structures. Just beneath the native copper there is some red cuprite inclusion too that runs across to the adjacent crystal too. The smaller crystals in the cluster are gemmy and clear, completely colorless and present as radiating sprays tucked away beneath the larger pair.

The condition is superb with contact only at the base area.
