Jeffersonite was once considered a distinct mineral but is now considered a zincian manganoan variety of Augite. According to the website for Monticello, the home of Thomas Jefferson, the mineral was named in 1822 to honor him for his contributions to the natural sciences. These three specimens are offered together as a lot because there was only one old label which appears to be for the largest. One of the specimens has some smaller, nicely formed crystals. The color is a dark chocolate brown. The specimen is in good condition with no appreciable damage.
