Quartz Shelter Stone Crag, Caingorm Mountains, Grampian Region, Scotland, UK FOV approx 8cm A selection of the odd-shaped smaller quartz crystals found at the same spot, none of them smoky. The longest crystal is 39mm. The thin flat one is 34mm x 19mm and 3-4mm thick. (Author: Mike Wood)

Quartz Shelter Stone Crag, Caingor

Quartz Shelter Stone Crag, Caingorm Mountains, Grampian Region, Scotland, UK 70mm x 35mm x 30mm A fairly large but rough looking quartz crystal. It is somewhat translucent and not smoky, and appears to have an overgrowth or second generation of quartz. Found this and several small crystals near the top of Shelter Stone Crag, by carefully climbing down a ’bottomless’ gully a short distance (not the gully in the previous photo). Couldn’t do much poking about as I was acutely aware of the sickening drop below me, and the possibility of climbers somewhere below. (Author: Mike Wood)
