EE14AF4: Gold (electrum variety) with Erythrite

A novelty at Sainte Marie-aux-Mines 2017. Strongly elongated and doubly terminated native Gold in hooked growths. They are on matrix with radial and felted aggregates of acicular Erythrite crystals. These native Golds from Bou Azzer were noted a long time ago so this recent rediscovery must be considered as a novelty; at the same time a curiosity and a rarity. We analyzed these Golds to confirm the presence of Silver and, effectively, they are 26.1 % Ag with a 0.8 % As. We’ll send a copy of the analysis to the buyer.
