Mineral Family: Dumortierite belongs to the Silicate family. Silicate minerals form the largest family of minerals, including more than 25% of all known minerals and 40% of all common minerals. In addition to being a major part of the Earth’s crust, Silicate minerals have also been found on the moon and in meteorites. Silicates are minerals which contain the elements Silicon (a light gray shiny metal) and Oxygen (a colorless gas). Together, these two elements form a tetrahedron – a shape similar to a pyramid – with a Silicon atom in the center and Oxygen atoms at each of the four corners. These tetrahedra connect with other chemical structures, in six different ways, to form various minerals and rocks. There are six main groups of Silicate minerals, and these main groups are further subdivided into secondary subdivisions, such as Quartz and Feldspar. Dumortierite is in the Nesosilicate family, which have isolated tetrahedra, (tetrahedra which are not connected to each other). Other Nesosilicates include the entire Garnet family, Kyanite, Peridot and Topaz.
Formation: Dumortierite is typically formed in aluminum-rich metamorphic rocks, created by contact metamorphism. Dumortierite is occasionally found in boron-rich igneous rocks.
Mining: Dumortierite is a secondary mineral found in aluminum-ore mines and garnet mines. It is used in manufacturing high-grade porcelain and ceramics, as well as an ornamental stone.
Enhancements: All Dumortierites may be considered fully natural, enhanced only by tumbling, cutting, or polishing.
History of Dumortierite
Dumortierite was discovered relatively recently and so is not included in any ancient or medieval lapidaries, texts that describe stones and their powers.
Dumortierite was named after the French paleontologist Eugene Dumortier (1801-1876). He had spent the first part of his life working as gilder, applying a thin layer of gold or silver to decorative items. By the age of 50, he was financially secure enough to retire from this career and focus full time on his passion for geology and paleontology. He amassed an impressive collection of fossils and also wrote a four volume paleontological work for the Rhone-Alps region of eastern France. Upon his death he bequeathed his fossil collection to the Natural History Museum in Lyons. In 1881, a new blue mineral was found in the Rhone-Alps and was named in his honor.

Healing Properties of Dumortierite
Spiritual: Dumortierite is a powerful aid for psychic perceptions including clairvoyance, clairaudience, and clairsentience. It can be used to open and enhance intuitive abilities as well as to help us to accept our gifts and feel empowered within them. Dumortierite brings inspiration, prophetic dreams, and messages from our spirit guides. It also shows us how us to more clearly verbalize our spiritual ideas and beliefs. This combination of inspiration and verbalization makes it an especially good crystal ally for astrologists, tarot readers, and other spiritually-based interpreters. Dumorteirite is attuned to the Third Eye Chakra and linked to the astrological sign of Leo. It is connected to the Element of Wind and vibrates to the number 4.
Emotional: Dumortierite is a calm, happy, comforting stone that helps us to trust that everything is unfolding as it should, even if we don’t understand the Divine Plan yet. It encourage us to relax and it heightens emotional intelligence. If we feel like fear is driving us into a panic, Dumortierite helps us to calm down, breath deeply, and look at our fear logically. Dumortierite gives us courage to move through the dark times in our lives and have faith that we will emerge safely on the other side. It helps us to stand up for ourselves and have emotional stamina. Dumortierite also encourages us to see “outsiders” as friends we simply haven’t met yet, and to be actively inclusive of others.
Mental: Dumortierite brings mental clarity. It encourages us to keep our perspective open and be willing to look at situations from other points of view. Dumortierite can help us to recognize compulsive behavior and our own bad habits and to calmly shift them towards a more healthy way of being. It reduces illogical stubbornness and increases patience and curiosity. Dumortierite is an excellent stone for enhancing pure mental abilities including linguistic skills, mathematics, abstract thinking, etc. making it an excellent totem for students and scholars. Dumortierite encourages memory retention, teaches problem-solving skills and invites us to look at problems as interesting challenges rather than difficult obstacles.
Physical: Dumortierite is used by metaphysical healers to treat forgetfulness and other “foggy” mental disorders as well as OCD. It is also believe to help reduce headaches, epilepsy and vision problems. Dumortierite is said to be helpful in treating addictions of all sorts. Metaphysical healers can also use Dumortierite to enhance their own skills and provide insight into the base cause of a condition, so that it can be understood and treated.
Always use wisdom when considering crystal therapies for healing.

I first met the owner of the lapidary at the 2006 Gem and Mineral show in Tucson, Arizona. At that time I was working for a crystal shop in Utah and was at Tucson primarily as a “pack mule” to help carry all the stones. It was generally agreed by our crew that the “Madagascar” tent contained the most beautiful stones in the entire show.
In 2014, I embarked on my first buying trip for Moonrise Crystals. The company I knew of only as “Madagascar” was the one company I was most determined to find and buy from. This lapidary company only sells at a handful of major gem shows. The only time they are in the USA is for the Tucson Gem Show. During the rest of the year, the lapidary hand polishes their stock and also does charity work in their local community. They continue to offer some of the most beautiful tumbled stones in the industry and are among my favorite suppliers.
In 2019, Moonrise Crystals and the Madagascar lapidary company joined together to financially support a rural school in Madagascar.
