Rare gem triplite specimen discovered in Tucson.

multicolour.com — Last year, while exploring some remote corner of the Tucson Gem and Mineral Show, Denver based gem and mineral dealer Morgan Sonsthagen came across an attractive bright pinkish-orange rock being used as a paper weight. That 150 gram rock turned out to be triplite, an extremely rare mineral found sparingly at a few localities throughout the world.
