Dumortierite is an aluminum borosilicate material, a family of minerals that produce stones with long, fibrous crystals. Stones like tourmaline and howlite are in the same family. These stones are recognized as much for their inclusions as their unique patterns.
Dumortierite has been used all throughout history, most notably in China as a substitution for lapis lazuli, but it has also been confused for sodalite. It has been used in making high grade porcelain for some time. Dumortierite went relatively unrecognized in jewelry throughout history, instead, it was considered to be a good ornament stone for carving and decoration. This is because only the highest grade of Dumortierite is facetable, and such is the case with our beads.
It was not ever recorded as a mineral until the early 1880’s in the French Alps, and it was named for French paleontologist Eugene Dumortier. It is most often sourced from Brazil or Sri Lanka when considered for jewelry making, and is sold most commonly as an inclusion found in quartz.
This stone is favored for its unique blue color, which is its most common hue, however rare forms of the material can come in brown (such is the case with sunset dumortierite), green, and rarest of all, purple or pink. In its most common blue form it is very useful as a throat chakra stone, as metaphysically it helps to calm the wearer and organize thoughts.
