Name:
Named for Clarence Sweet Bement [1843-1923] by George Augustus Koenig in 1887. Bement assembled the finest mineral collection in the USA. He also assembled the finest collection of U.S. coins and was interested in a variety of collectibles. Bement had a keen interest in Franklin, New Jersey minerals from whence his namesake was discovered.
