This is a relatively HUGE triplite crystal that shows off like a red windowpane, fully translucent with even only a small amount of lighting. The crystal is terminated, although its unusual shape was constrained by growth in a thin vein pocket - which makes these distinct from all others of the species I have yet seen. nearly a floater, almost complete all around except a few minor contacts. Although the termination is irregular, it is there. There are substantial, large gem areas to this crystal that could be cut - significant in such a rare and colorful species. Mass is approx. 27 grams!
