Quartz, Druzy var.

Quartz, Druzy var.

Bryn y Rafr mine, West Wales. There is nothing unusual or spectacular about this specimen. I have included it simply because it is part of my collection. This is a vugh of minute dark coloured druzy quartz crystals no more than a quarter of a millimetre in size. There is a small amount of lighter coloured quartz around the edges of the vugh.
