Mineral Family

Dumortierite is a nesosilicate mineral.  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. Dumortierite belongs to the nesosilicates group, in which the Silicate tetrahedra are not directly attached to each other.

Dumortierite’s energy works well with its family – other nesosilicate minerals.  Try it in combination with Chiastolite, Garnet (Almandine, Grossular, Hessonite, Rhodolite, Uvarovite), Kyanite, Peridot, and Topaz

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.  It 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.
