Response to Dial Materials- What are they?

 

Dumortierite is named for the French paleontologist, Eugene Dumortier who discovered it in 1881. It is a boro-silicate mineral. Notable Occurrences include the type locality of Beaunan, France as well as Quartzite, La Paz County, Arizona; Colorado; Oreana, Nevada; New York, New York and Alpine, San Diego County and Los Angeles County, California, USA; Magadanskaya, Siberia, Russia and Sahatany, Madagascar.

Color is typically blue to violet, but also pink and brown and has a hardness of 7 to 8.5 (Mohs'). Interestingly, it has been used in the past as an imitation lapiz lazuli in carvings. It is the most common boro-silicate with the exception of the Tourmaline group. It is used in the manufacture of high grade porcelain.

If you're interested in the metaphysical properties of this stone, dumortierite 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. (this sounds like a good dial material for me)
