SV21800NXF: Nagyágite with Sylvanite and Quartz

An important piece due not only to the minerals that form it, but by the very association of both species on the same piece, which is not common. Metallic grey Nagyagite crystals with preferentially oriented growths, are implanted in a slightly pink crystalline Quartz matrix and accompanied by darker lanceolate crystals of Sylvanite. A historical specimen, obtained at the end of the 19th century, from a classic mining district in Romania that has deposits in which gold, silver and tellurium are exploited and that is the type locality (TL) for Nagyágite. From the collection of Ignacio Gaspar Sintes whose handwritten record we will send to the purchaser.

TV86AF7: Djurleite-Chalcocite intergrowth

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)

TC86AD5: Gold

A novelty at Tucson 2016. Parallel aggregates of very sharp and well defined octahedral crystals, with sharp skeletal growths. According to our sources the site is 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.

MMX96AN9: Franklinite with Calcite

Octahedral crystals of Franklinite with very sharp crystal forms and with the dominant octahedron beveled by the dodecahedron. One of the crystals is clearly dominant and very aerial on a Calcite matrix. We emphasize that the crystal, in addition to being very aerial and complete, is practically free of damage, something really unusual in this type of specimen. To all this we must add that the specimen comes from the prestigious collections of John Kolic and Chester Lemanski.

ERB96AN4: Chalcocite

New discovery: very aerial group of Chalcocite crystals, huge for the species, between platy and tabular, very sharp, with a pseudo-hexagonal outline and great luster. This specimen, of high quality for the species, comes from new workings in the M'Passa area where a group of small mines used to produce, in their glorious past, specimens with large sharp crystals. With the closure of the workings in the 1980s, that glory was lost, although fortunately it has now returned with specimens as magnificent as those and, moreover, with a great variety of crystallographic habits.
