Summary[edit]

Description
English: Acanthite
Locality: Chispas Mine (Pedrazzini mine), Arizpe, Municipio de Arizpe, Sonora, Mexico (Locality at mindat.org)
Size: cabinet, 12 x 8 x 7 cm
Acanthite
It was an honor to hold this piece...my hands have seldom trembled, but it was humbling to be entrusted with such an incredible specimen. It is hard to appreciate this piece, until held in the hand. It has such dimensionality, such geometry, that it looks man-made and like no other acanthite I have seen in nature. It is an order of magnitude more important and impressive than any other Mexican acanthite I have seen , excepting only the famous Houston Museum specimen. And, for a "black mineral" it has remarkable aesthetic and display impact. The piece is simply mesmerizing....and note, this is not my own opinion only, but shared by many others who have seen the specimen over the decade it was on loan to a public museum; and by many collector specialists who know far more about silver species than I do. In fact, I have heard many collectors pronounce this to be the finest example of acanthite from ANY locality, as Dr. Terry Wallace and Dr. Wendell Wilson convey in the Romero Collection book where they add: This specimen is widely regarded as the finest example of the species in existence. It was originally collected by (mine owner) John Pedrazzini around 1890 and may have been among the spectacular specimens that he exhibited at the 1893 World's Columbian Exposition in Chicago.He eventually presented it to Mexican mineralogist Prof. Eduardo Schmitter Villada (1904-1982) , who later gave it to Migrual Romero (as a gift to his former graduate student). Mining here ceased in 1930. This cabinet-sized specimen is considered to be one of the greatest treasures of the Romero collection. Some people who have seen the collection ranking this even ahead of the famous Aztec Sun legrandite in importance and beauty! Once a core specimen on display in both his museum, and later for a decade in the University of Arizona Mineral Museum on loan from the Romero family.

Ce fut un honneur de simplement tenir cette pièce ... mes mains ont rarement tremblé, mais on se sent petit lorsqu'on vous confie un spécimen aussi incroyable. Sauf à la tenir en main, il est difficile d'apprécier cette pièce. Ses dimensions et sa géométrie sont telles qu'elle semble un produit de l'artisanat humain et ne ressemble à aucune autre acanthite que j'ai pu voir dans la nature. Elle plus grande et impressionante que n'importe quelle autre acanthite mexicaine que j'ai vu, excepté le fameux spécimen du Houston Museum. Et, pour un "minéral noir", son esthétique est son aspect sont remarquables. La pièce est tout simplement fascinante .... et notez que ce n'est pas seulement ma propre opinion, mais celle de beaucoup d'autres qui ont vu le spécimen durant la décennie ou il fut en prêt dans un musée public, ainsi que celle de nombreux collectionneurs spécialistes qui en savent bien plus que moi sur les pierres d'argent. En fait, j'ai entendu de nombreux collectionneurs la désigner comme le plus bel exemple d'acanthite jamais trouvé. Le Dr Terry Wallace et M. Wendell Wilson ajoutent même, dans le livre consacré à la collection Romero : "Ce spécimen est largement considéré comme le plus bel exemple de spécimen connu". Elle a été initialement récoltée par John Pedrazzini (propriétaire de mine) vers 1890 et pourrait avoir été parmi les spécimens spectaculaires qu'il a présentés à l'Exposition universelle de Chicago en 1893. Il l'a pour finir offerte au professeur Eduardo Villada Schmitter (1904-1982), minéralogiste mexicain qui l'offrit ensuite à Miguel Romero (comme cadeau à un ex-étudiant). L'exploitation minière cessa à Las Choyas en 1930. Ce spécimen de taille "cabinet" est considéré comme l'un des plus grands trésors de la collection Romero. Certaines personnes qui ont vu cette collection jugent même qu'il surclasse en importance et en beauté la fameuse legrandite dite "Soleil aztèque" qui y figure aussi ! Pièce maîtresse d'exposition dans son propre musée, puis, durant une décennie au Musée Minéralogique de l'Université d'Arizona sur prêt de la famille Romero.
