Dumortierite is a fibrous variably colored aluminium boro-silicate mineral, Al7BO3(SiO4)3O3. Dumortierite crystallizes in the orthorhombic system typically forming fibrous aggregates of slender prismatic crystals. The crystals are vitreous and vary in color from brown, blue, and green to more rare violet and pink. Substitution of iron and other tri-valent elements for aluminium result in the color variations. It has a Mohs hardness of 7 and a specific gravity of 3.3 to 3.4. Crystals show pleochroism from red to blue to violet. Dumortierite quartz is blue colored quartz containing abundant dumortierite inclusions.
Dumortierite was first described in 1881 for an occurrence in Chaponost, in the Rhône-Alps of France and named for the French paleontologist Eugene Dumortier (1803-1873). It typically occurs in high temperature aluminium rich regional metamorphic rocks, those resulting from contact metamorphism and also in boron rich pegmatites. The most extensive investigation on dumortierite was done on samples from the high grade metamorphic Gfohl unit in Austria by Fuchs et al. (2005). Dumortierite was named following the French scientist, M.E. Dumortier.
It is used in the manufacture of high grade porcelain. It is sometimes mistaken for sodalite and has been used as imitation lapis lazuli.
Sources of Dumortierite include Austria, Brazil, Canada, France, Italy, Madagascar, Namibia, Nevada, Norway, Poland, Russia and Sri Lanka.
Dumortierite is a stone that’s similar to kyanite, in that it enhances the abilities to break through barriers and it contains the mineral, Boron. This stone acts as an aid to your mental capabilities in overcoming tough situations. It opens the third eye chakra to enhance mental (and emotional) intelligence. Dumortierite promotes mental discipline especially in regard to learning new things. Students find it useful when they are required to take in large amounts of data over short periods of time, because it aids memory.
This enhancement is believed to be due to the effect it can have of balancing the throat chakra and enhancing communication between lower chakras/physical energy and the higher chakras/mental/spiritual energy. It highly reduces difficulties of scattered mind and disorganization. In addition, it encourages one to see and accept reality, and react to it in an intelligent manner in one’s own behalf
