For those who collect aesthetic display rarities,this is one sure to stump most people into guessing it is Libethenite or Malachite first. NOTE ADDED FROM CURATOR Pierre-Jacques Chiappero of the Parisian National Museum: I write you about your specimen of atacamite TUC 102-08. I recognize immediatly the origin of this specimen. It belongs to the Vesignie collection. The name atacamite and the catalog number 2950 A had been written by him. Vesignie bought this specimen from the Parisian mineral dealer Deyrolle in june 1930 for 81 french francs. The initial handwriting give the locality in french that i can translate by from the copper mines of Naltagua near Las Casas in Santiago province, Chile. This specimen was obtained by the Museum in 1955. It was probably exchanged to a collector or a dealer during the sixties.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",1138,1500,{"id":583,"source_url":584,"license_code":484,"credit_html":585,"title":586,"description":587,"author":488,"original_width":304,"original_height":588},34177,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10478677","Robert M.

This is the very uncommon habit of GEMMY, transparent, elongated crystallization that is seldom seen in the species in this quality - and the best is very old material. This material is EXTREMELY HARD to come by today, as most was mined prior to 1930 or so. Many specimens are turn of the 1900s. To get such fine crystals is hard enough, but pristine ones, in a protected pocket like this...forget about it. I was shocked when I saw this specimen. Usually, the crystals of this habit are all banged up from handling, but these pocket crystals are, instead, pristine and jewel-like in their lustre and flash. Again, they are actually gemmy when backlit. Unlike most such examples, this can also be safely sent through the mail. Old material, superb for the species, and seldom seen, this is one of my favorites of the update.

Atacamite takes it from the Atacama Desert of northern Chile, the hyperarid landscape where the first specimens were gathered.\n\nThose specimens were collected in 1801. The following year the mineral was formally described and named by Dmitri Alekseyevich Golitsyn[1], a Russian diplomat and naturalist. He chose the desert that had yielded it — the type locality — as its namesake[2].\n\nThe bright green of atacamite found a use in art long before chemists pinned down its formula. It has been identified as a pigment on sculpture, manuscripts, maps, and frescoes across Asia, Russia, Persia, and Europe[3].\n\nThe mineral also turns up where no human put it. In 2002, researchers reported it as the first copper biomineral known in a living animal — the crystalline mineral that hardens the jaw tips of the marine bloodworm *Glycera dibranchiata*[4]. The worm builds those jaws from roughly ten parts protein to one part mineral, yet they resist wear about as well as the toughest materials made by hand[5].","claude-opus-4-8","1.7.0",{"markdown":928,"model_version":925,"prompt_version":926,"reviewed_at":11},"Atacamite is a copper mineral, so where it gathers in quantity it can be mined for the metal it holds[1]. It is only ever a minor, secondary ore, though. It forms in the weathered upper layers of copper deposits rather than in the rich primary rock below, and it is far too scarce to rival the sulfide and oxide ores that supply most of the world's copper.\n\nBeyond that limited role, the mineral has little modern industrial use. Its sharp green crystals are prized mainly by collectors and museums as well-formed examples of a copper chloride.\n\nThe mineral also draws scientific interest of its own. The copper biomineral that hardens the jaw tips of bloodworms — atacamite — is studied as a design prototype for tough, lightweight, durable materials[2]."]
