Cesium-rich beryl has been known for a long time, and occurrences are not exactly rare. At the Tucson Gem and Mineral Show® in February 2003, the appearance of what were originally thought to be a cesium-rich beryl caused a stir because these had a deep pink color, and many were of gem quality. Even more excitement ensued once it was determined that these newcomers represented not only a source for new material but also a new mineral species.
