Preseli Bluestone
The Ancient Blue Voice of Stonehenge
Also known as: Stonehenge Stone, Preseli Spotted Dolerite
About the stone
Preseli bluestone usually refers in the gemstone trade to spotted dolerite, a blue-gray to greenish rock with pale mineral flecks, sourced from the Preseli Hills of Pembrokeshire, west Wales. Known to Neolithic people who transported stones from this region to Stonehenge, it has no single recorded discoverer; geologist H. H. Thomas established the Preseli connection in 1923, while later research identified Carn Goedog as a principal source of Stonehenge’s spotted dolerite. Also called “Preseli stone,” “preselite,” or marketed as “Stonehenge bluestone,” it should not be confused with every Stonehenge bluestone, a collective term covering several rock types. Its lore includes medieval stories of Merlin transporting magical healing stones to Stonehenge, while modern crystal traditions associate it with grounding and ancestral connection.

Care and handling
Preseli Bluestone is a hard, dense rock and very durable. Clean it with lukewarm water and a soft brush or cloth, then dry it well. It tolerates handling well, but avoid dropping heavy pieces on tile or stone floors, which can chip the stone or the surface beneath. Polished pieces may dull if scrubbed with abrasives, so use gentle cleaning only.
Individual experiences with Preseli Bluestone vary, and its effects are deeply personal. Hold it mindfully and let its long history remind you of the patient, enduring strength of the Earth.
