Quartz crystals.

Llawr y Glyn, Nr. Staylittle, Central Wales. This unremarkable specimen is included in my collection simply because it was one of my earliest collected specimens over twenty years ago. The specimen simply fell out of a roadside embankment, unusual because the nearest mine workings are about two miles distant, perhaps indicative of an undiscovered mineral lode close by.
