Alleghanyite is an exceptionally rare member of the humite group, and this specimen is unusually rich with gemmy brown microcrystals to 2 mm flatlaying along an approximately 3-cm vertical axis on this specimen . The matrix is a typical mix of franklinite/calcite/willemite and is highly fluorescent. 11 x 6.5 x 4 cm
MD-70403 - Alleghanyite - - Archived Sunnyside Mine (American Tunnel; Mogul Mine; Washington Mine; Belle Creole; Gold Prince; Brenneman Mine; Sunnyside Mine Group), Howardsville, Silverton District, San Juan Co., Colo small cabinet, 6.8 x 5.6 x 3.7cm
These crystals, despite their size, are some of the finest color, exceptionally well crystallized Alleghanyites you''ll see from any locality. Typically Alleghanyite forms in pinkish-grey or pinkish-brown color crystals, if they''re even crystallized at all (most Alleghanyite I''ve seen is anhedral and good crystals are few and far between in this world. With that said, the crystals on this piece are wonderfully crystallized and have a superb vibrant pink color. The color is truly as good as any locality gets. The crystals are rather small (mostly micros), but there are dozens upon dozens of them loaded in/on a massive lighter pink color Pyroxmangite matrix with minor sulfides and Quartz. This is XRD confirmed Alleghanyite, and could actually be broken up into several killer micromounts that would satisfy plenty of collectors. 6.8 x 5.6 x 3.7cm All Content and Design ©1996-2010 The ArkenstonePowered by http://mineralwebsites.comBy-species Galleries | ||||
