Diaspore.
ER98AL9: Diaspore
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.

Djurleite-Chalcocite intergrowth.
TC88AF7: Djurleite-Chalcocite intergrowth
A novelty at Tucson 2017. Parallel growth of very flattened and bright crystals. These samples were mined carefully over seven months in the Aït Ahmane area (it seems not in the same shafts that produced the famous Gersdorffites) and, due the sharpness of the crystals and their size, this find will contend for being the world's best for the species. We’ll send to the buyer a copy of the analysis that indicates an intimate intergrowth of Djurleite and Chalcocite.
