Lustrous, emerald green Pseudomalachite has coated a matrix of Quartz crystals with a rich, colorful druse. The central, and largest, Quartz crystal is 4 cm in length. This old-time specimen, attractive and balanced, is from the heart of Cornwall. Most unusual, the only one I have seen like this is from the Old Gunnislake Mine (which I am assuming this also would be). Old Ward's Label included.
