Ningyoite - Sold

Ningyoite is a hydrous uranium phosphate mineral, specifically a member of the rhabdophane group. Muto et al. (1959) named the mineral after the Ningyo Pass, site of the type locality. Ningyoite forms minute crystals (ca. 5 microns) in sandstone, and constitutes the principal uranium ore at this locality.
