Superb, gemmy crystal from the pocket or zone that produced these green and blue striped crystals over the past year or so. The crystal is wide and thin showing a central blue stripe up the center of the mai face with green zones on either side. Viewed through the side it is a deep purple color with a red/purple up the C-axis. There is very minor chipping along the termination - do not be fooled by the many litle growth hillocks on the crystal faces near the termination which can give the impression of damage in the photos. This is a top notch crystal, amazingly gemmy and bright.4.2 x 2.6 x 0.9 cm.
