Description
Dumortierite ranges from very deep navy blue to a lighter blue, to a rare violet. It was first described in 1881, and named for French paleontologist Eugene Durmortier (1803-1873). Some stones may also show areas of brown, pale orange, pink, a bluish-green, and green. Often confused with Lapis Lazuli, Dumortierite also looks similar to Sodalite. The differences are that natural Lapis has streaks of Goden Pyrite, and Sodalite exhibits small-to-large areas of White Calcite. Most gem-quality Dumortierite is found in Nevada (USA). Other localities include Australia, France, Madagascar, Mozambique, Norway, South Korea, Sri Landa, Canada, Poland, Namibia and Italy.
