Dumortierite Meaning and Properties
Dumortierite History
Deep blue dumortierite is called the "blue denim stone." It is named for a French paleontologist, Eugène Dumortier, who discovered it in 1881 in the Rhône-Alps region of France. Dumortierite is used to manufacture high grade porcelain. It is sometimes mistaken for sodalite and lapis lazuli. Because of the perceived similarity, dumortierite is often used as a cost-saving substitute for lapis which costs two to three times as much.
What are the Metaphysical Properties of Dumortierite?
Dumortierite is believed to be a stone of self-reliance and discipline. Dumortierite meaning is associated with patience and orderliness. The stone is credited for promoting insight and aiding memory. Dumortierite meaning is also linked to mental clarity and communication skills.
What is Dumortierite Made From?
Dumortierite crystals are formed most often in metamorphic rocks that are rich in aluminum and under high temperatures. The vitreous crystals' colors range from brown to blue and green, as well as more rare pink and violet. Color variations occur with the substitution of iron and other elements for the aluminum.
Dumortierite is found in Brazil, Europe, Sri Lanka and Peru, as well as in the United States and Canada.
