Close-up of the pegmatite vein pictured above. The vein is approx. 2ft (60cm) thick. Only the inner part is truly pegmatitic; the outer two parts of the vein are composed of either fine-grained granite, or aplite rock. But free grown crystals of quartz for example are very rarely found in these veins. (Author: Mike Wood)
