Minerals have played a major role in the economic and social development of Wales since the Bronze Age. Since these ancient times, mineral outcrops and mines have been worked throughout Wales; by Romans and Cistercian Monks, and on into the heyday of Welsh metal mining in the mid nineteenth century, when virtually every outcropping vein or fault was tried by the drivage of adits or the sinking of shallow shafts.
There are currently around 4,900 officially recognized mineral species known to occur globally, of which, 430 have been confirmed from Wales.
Here we present a gallery of Welsh minerals for you to enjoy the incredible colours, forms and lustre of these magnificent museum specimens.
