This superb thumbnail is highlighted by a sublime, gemmy, 1.7 cm, doubly-terminated Mimetite that sits high on the matrix, accented by several other quality crystals. From the world-famous "Gem Pocket' of the early 70's. Aesthetic and world-class competition-quality thumber....it is just unbelieveable that something like this actually SURVIVED, to me! 2.6 x 2.4 x 1.7 cm
