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 an excellent historical pseudobrookite (a rare Fe-Ti oxide) specimen from Thomas Range, Utah! It features an undamaged spray of metallic crystals in a quartz vacuole ideally positioned in the centre of a clear rhyolitic host rock. A beautiful American classic!
