MD-249212 - Linnaeite - - Archived La Motte Mine, Mine La Motte, Fredericktown District, Madison Co., Missouri, USA thumbnail, 2.4 x 1.7 x 1.4 cm.
2.4 x 1.7 x 1.4 cm. Linnaeite is an uncommon cobalt sulfide. The matrix on this old-time thumbnail is richly covered with sparkly linnaeite microcrystals and massive, layered linnaeite. The linnaeite has an interesting purple iridescence. This rich and highly representative piece is from the historic La Motte MIne of Madison County, Missouri in the old Missouri Lead Belt of southeastern Missouri. This is the oldest lead mine west of the Mississippi River, opening in 1720. Classic material accompanied by an expertly handwritten, faded label from an older collection. The collection this came out of was a museum stash dating to prior to World War I.
MD-51413 - Linnaeite, Chalcopyrite - - Archived Victoria Mine, Littfeld, Siegerland, North Rhine-Westphalia, Germany miniature, 5 x 4 x 2 cm
Linnaeite is a rare cobalt sulfide (CoCo2S4), first found in Sweden and named after the famous botanist Carolus Linnaeus. This antique German specimen evidently passed though a couple of old German collections before ending up in the collection of Paul Jung, which is now being dispersed. It features several crystals of this very rare species to 6mm in size, set in massive linnaeite and chalcopyrite. 5 x 4 x 2 cm All Content and Design ©1996-2010 The ArkenstonePowered by http://mineralwebsites.comBy-species Galleries | ||||||
