Prenteg, just northwest of the village of Tremadog (formerly Tremadoc) in Gwynedd, Wales, is famous for it Alpine-type mineralisation and for being the type locality of Brookite.  From the Alpine-type clefts, fine Quartz crystals were collected and this choice small miniature is a beautiful example of the variety ‘Rock Crystal)’. Two double-terminated transparent Quartz crystals, 3.5 and 4 cm long, grow attached to each other along a common prism face with two much smaller but similar crystals attached.  Text can be easily read through the water-clear crystals.
