This beautiful stone is typically blue or violet in color, ranging from a very deep navy blue to a lighter blue, to a soft violet. Often confused with Lapis Lazuli, Dumortierite also looks similar to Sodalite. The differences are that natural Lapis has streaks of Golden Pyrite, and Sodalite exhibits small-to-large areas of White Calcite. Some varieties of Dumortierite also show areas of brown, pale orange, pink, a bluish-green, and green. Most gem-quality material is found in Nevada (USA). Other localities include Australia, France, Madagascar, Mozambique, Norway, South Korea, Sri Lanka, Canada, Poland, Namibia and Italy. Geologically speaking, Dumortierite is an aluminum borosilicate mineral that varies in color from blue, green and brown to a rare violet and pink. First described in 1881, the mineral was named for French paleontologist Eugene Durmortier (1803-1873).
