D10-57 - Allophane - $ 450 SOLD Graphic Tunnel, Kelly Mine, Magdalena District, Socorro Co., New Mexico small cabinet, 8.6 x 6.6 x 4.6 cm ex. Al Ordway
A beautiful, intense blue specimen of the rare aluminum-bearing silicate allophane. It has a waxy and vitreous lustre to it that is different than the similar-appearing chrysocolla (copper-containing). I had not seen this mineral from the Kelly Mine, but I am very much inclined to trust Al's judgement and labelling. The man was field-collecting since before my parents were born, and he has been all over the place building his large reference collection.
MD-228357 - Allophane - - Archived Astentofern, Hüttschlag, Großarl valley, Radstädter Tauern Mts, Salzburg, Austria small cabinet, 7.6 x 4.4 x 2.6 cm.
7.6 x 4.4 x 2.6 cm. Beautiful, botryoidal, sky-blue allophane with a pearly lustre and amorphous, pastel-green to tan allophane richly and showingly coats the top of the mica schist matrix on this old-time Austrian specimen. The ancient mines at Astentofern worked locally enriched sulphide impregnations in green slates. Comes with 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. All Content and Design ©1996-2010 The ArkenstonePowered by http://mineralwebsites.comBy-species Galleries | ||||||
