Mostly new after the Sainte Marie 2020 Virtual Show, from a classic Turkish locality but with a different transparency and color. The crystal is incomplete at the bottom, but has very sharp polycrystalline upper terminations. It is transparent, lustrous, deep yellow-green in focused natural light and more yellow under halogen lights, with very clearly visible dichroism shifting between soft red and green.

TC88AF7: Djurleite-Chalcocite intergrowth

A novelty at Tucson 2017. Parallel growth of very flattened and bright crystals.
