A rich coating of lustrous apple-green crystals on a gemmy Quartz crystal. The Philipsburgite crystals are classic for the type locality - gemmy, rounded to about .5 mm in size, lustrous, and an attractive medium green. On one area they are spread out so they can be appreciated individually, on another part of the specimen they form a dense coating. Ex. Charlie Key.
