Preseli Bluestone is a rare variety of Dolerate, an igneous rock.  It is found only in the Preseli Hills of Wales in the United Kingdom.  It’s great claim to fame is that these stones form part of Stonehenge, a famous prehistoric monolith in southern England.  According to legend, the stones were brought by magic by the wizard Merlin in the years before King Arthur’s court.  When left rough, it is a blue-grey stone, but when polished Preseli turns bright green.  Energetically it is unsurprisingly tied to the energy of the Old Ways, of druids and the shamans of old Europe.  It is highly recommended for mystics that delight in the natural world and its rhythms.

Where does Preseli Bluestone come from?

The only deposit of Preseli Bluestone is Preseli Hills in Western Wales.

Mining and Treatments

The original Preseli Bluestone came from Carn Meyne, a rocky outcropping in the Preseli Hills of Western Wells. Today, Carn Meyne is protected from both commercial mining and amateur rockhounds, so it is illegal to remove any stones from Carn Meyne or the immediate surrounding area. Some of the Preseli on the market comes from private sources of stones that were taken from the mountain before any laws were put in place. Recently, a small business near Preseli Hills has secured exclusive rights for quarrying. The stones do not come from Carn Meyne, but rather a nearby location and are geologically identical.

Green Dolerite from other locations have on occasion been sold as “Presli Bluestone”. True Preseli Bluestone comes from Wales and will contain white spots, although depending on the size of the stone, spots may or may not be present! Always buy from a reputable seller. Preseli Bluestone are fully natural, and not enhanced in any way besides cutting, tumbling and polishing.

Mineral Family

Preseli Bluestone  is not a mineral, but rather an altered igneous rock. As an easy way to understand the difference, think of rocks as being like cookies and minerals as being the ingredients which make up those cookies. Many different minerals are used to create a rock! In the case of Preseli Bluestone, the rock is a rare variety of Dolerate (more commonly called Diabase in North America). The main chemical element is Calcium and the major minerals are Feldspar (green) and Augite (black). Many stones are also flecked with white chalk or Snow Quartz.

History of Preseli Bluestone

Preseli Bluestone has a very unique metaphysical history. Thousands of years ago it was one of the stones used to build perhaps the most famous prehistoric structure in the world – Stonehenge. But, then it was largely forgotten, its healing powers remembered only in local folklore and lengend in western Wales. In the twenty-first century, Preseli Bluestone was re-introduced to the global healing crystal community after a team of geologists and historians determined the it was used to build the inner ring of Stonehenge. Overnight, Preseli Bluestone became an immensely popular stone, helped in part by it’s reported metaphysical powers as well as the very limited supply.

This stone goes by many names, Preseli is reference to the Preseli Hills in Western Wales, where this stone is mined. It is also called “Bluestone”, which can be confusing to collectors when they first see polished specimens. In its roughest form, the stone often appears blue-grey, but it takes on a blue-green color when polished or tumbled. While Dolerite (also called Diabase) is a relatively common igneous rock, the particular variety called Preseli Bluestone has been metamorphosed and has white spots on it, a trait unique to a very small region in Pembrockshire, Wales.

Stonehenge is a prehistoric structure located in southern England which was built sometime between 3100-2200 BCE. The archaeological evidence largely suggests that it was built gradually and added on to over the course of that 900 year period, rather than constructed at a single time.  A variety of different stones were used in its construction, with Preseli Bluestone being added in 2900 BCE, before the giant sarsens were added.  The culture that created it had no written language, and so Stonehenge’s purpose and methods of construction will probably always be open to debate. One fact that is undeniable is that Stonehenge was purposefully designed to align with the solstices, although for what purpose we will never know. For centuries, many civilizations worldwide have looked to the solstices and equinoxes as a time of celebration and spiritual reflection, and it is reasonable to suppose this would have been true in prehistoric England as well. Recent archaeological digs have also firmly established that Stonehenge was a burial site, although who exactly was buried there and why remains a subject of debate.

Stonehenge, Preseli Bluestone


Equally mysterious is the question of HOW it was built, since it is composed of enormous stones that come from a mountain range more than a hundred miles away, and was built before the wheel was introduced to Britain. For centuries the obvious conclusion was “magic.” Many have said it was the Devil that moved them, who stole them from a greedy old woman.

But since the 12th century, the primary individual credited with building Stonehenge is Britain’s most powerful wizard, Merlin. The legend was first mentioned in Geoffrey of Monmouth’s Historia Regum Britanniae – a history of Britain which is one of the primary sources for the beloved story of King Arthur. In it, the stones were originally from Africa and brought to Ireland by a race of giants who danced around them and infused them with healing power. Merlin brought the stones to England using magic and his connections with the Giants, and erected it on Salisbury Plain as a war memorial for King Aurilius Ambrosia. As the story continued, after Aurilius Amborsia’s death he was buried at Stonehenge, and he was succeed as High King by Uther Pendragon, who in turn was succeeded by his son Arthur.

Among the local people who live near Preseli Hills, a common folk-remedy for healing is to soak a small piece of Presli Bluestone in water and to drink the elixir. This type of practice is well documented throughout formerly Celtic lands. Elixirs made from “holy stones” were said to cure a wide assortment of diseases.
