ET86AF7: Aggregate of deformed and rounded crystals. A curious growth that is the result of the removal of copper during the mining in which the copper recrystallizes sometimes acquiring the shapes of the objects and machines it has grown on.
In other words, this copper has been formed naturally but is "neoformed" since its origin may be due to human activity in an old abandoned mine.
Zlaté Hory, Olomouc Region, Moravia  Czech Republic (04/2014)

Djurleite-Chalcocite intergrowth

TC88AF7: 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.
Aït Ahmane, Bou Azzer District, Tazenakht, Ouarzazate Province, Souss-Massa-Draâ Region  Morocco (11/2014-05/2015)

Specimen size: 2.2 × 2 × 0.6 cm = 0.9” × 0.8” × 0.2”

TV86AF7: A novelty at Tucson 2017. A cluster, on matrix, of very sharp and flattened crystals with a pseudohexagonal contour. These samples were mined carefully over seven months in the Aït Ahmane area (it seems that not in the same shafts that produced the famous Gersdorffites) and, due the sharpness of the crystals and their size, this find will highlight between 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.
This sample has been referenced and figurate, as a novelty in Ste. Marie 2017, in the magazine "Le Règne Minéral" (Num. 136. 2017; page 47)

Gold

TY59AF7: Floater and complete specimen with parallel and deep skeletal growths of octahedral crystals with very well defined faces and edges. The site is currently not supplying new specimens for collectors so new finds are not expected. We analyzed these Golds and they are really special. They contains a 99.1% Gold and about a 0.5 % Rhodium, which is quite uncommon. We’ll send a copy of the analysis to the buyer.
