Ex. Les Fils d'Émile Deyrolle (Paris, 1896-1950's). Comes with the typical Deyrolle box and old label.
In June last year, Alain Martaud and I acquired parts of an old family collection in Marseille, gathered up between the late XIXth century and the 1960's by successive generations of collectors (probably city dignitaries).
This collection featured hundreds of specimens that were exclusively purchased from Deyrolle, a prominent Parisian naturalist dealer in this period, and had been kept stored in their original box until today, carefully sorted in several custom-made wooden mineral drawer cabinets.
The specimens by themselves date back from the early XIXth century up to the first half of the XXth century and consist mostly in European and American classics, as well as rare species and systematics ore samples.
Here is a remarkable old specimen from Sankt Andreasberg, Harz!
It displays several masses of native silver made up of small wires with delicate patina, on translucent quartz with short prism crystal habit. Notice also numerous small blebs of lustrous silver colour acanthite all over the quartz crystals.
A superb historical gold from a famous German historical locality for silver minerals!
