JFD42AL5: Allargentum with Actinolite (variety byssolite) and Calcite

Very dominant elongated crystals of Allargentum, with intergrowths of Silver and Dyscrasite, on a Calcite matrix with centered growths of acicular crystals of Actinolite (byssolite variety). The Allargentum appears to be clearly the majority in the two analyses (EDS and XRD) carried out on the specimen, demonstrating that it is not a pseudomorph but rather Allargentum crystals intergrown with Dyscrasite and Silver. It comes from the Jordi Fabre collection. We'll send to the buyer a copy of the analysis and both Jordi Fabre collection labels, the original label (F1765) as well as the Internet label (JFD42)

EBB47CD3: Allargentum with Silver (variety Hg-bearing)

Aerial growths of Allargentum that appear intergrown with Silver with a high mercury content, with some of the faces being well defined, and with small remnants of Calcite which has been acid-etched to reveal the sulfides and native elements. These are important crystals for the species Allargentum, which is a much rarer species than Dyscrasite. In fact, until the appearance of these Bouismas allargentums, quality specimens were hardly known and, in general, had poorly defined crystals. The piece has been analyzed and we will send a copy of the analysis to the buyer.
