About Preseli Bluestone Crystal Tumbles
Preseli Bluestone is actually the same stone that was used for the inner ring at Stonehenge. These stones came from the Preseli Hills in Wales, 200 miles from Stonehenge. Preseli Bluestone is said to be an extremely healing crystal, one that is strongly connected to the Earth. Maybe this was why it was used at Stonehenge!
