These three minerals you cannot discern with any confidence. Basically they are light to dark green. The Pryite is easily recognized, of course. There is probably Talc and Anthophyllite in the specimen as well. A label from the Cureton Mineral Co. founded by the late Forrest Cureton comes with the specimen. Forrest was a great mineralogist, a friend of mine.
