Adams Mine, Cement Creek, San Juan Co., Colorado, USA
Thumbnail, 2.1 x 1.6 x 1.5 cm
Ex. William Panczner

A very rare example of the famous Colorado Hubnerites, among the more pure end-form members of the species. Considered rare collectors items by Colorado devotees, this is a particularly aesthetic thumbnail, as it is on matrix and has some good color to it. The crystal is just over 2 cm tall. From the award-winning thumbnail collection of Sharon and William Panczner, author of the book Minerals Of Mexico, and last seen and exhibited in the 1960s.
