EB87T4: The Allargentum, as very well defined crystals, appears intergrown with Silver and Dyscrasite, forming dendritic growths on a Calcite matrix. The Allargentum is dominant in the analysis so, following IMA recommendations, we label the sample in this way. We'll send a copy of the analysis to the buyer.
