Preseli Bluestone is the same stone that the ancient monoliths at Stonehenge are constructed from, so unsurprisingly it is strongly connected to the ancient Celts!   Mined from the Preseli Mountains in Wales, Preseli Bluestone contains feldspar and white quartz, which gives it a beautiful, mottled appearance.   The name is sometimes a bit confusing because this crystal is not always very blue, and sometimes the polished stone looks more green or greyish in colour. Bluestone is believed to aid and enhance your spirituality and tap into the mystical energy of Merlin and his magic.
