Nice old stock specimen of Beryl with Muscovite from Smedley Park Pennsylvania . This is A very rare and large crystal from this locality . Please note some images are shown with a backlit flashlight . Also note that the flashlight made blue areas on the images that are not really blue ,just the way the picture came out . There is a ruler for size and the specimen measures about 3 1/2" long and the actual beryl crystal is about 1 3/4" .
