Dumortierite, also called the blue denim stone, is named after Eugène Dumortier, a paleontologist from France that discovered it in the Rhône-Alps region in 1881. The stone brings a calm, focused, and clear mind which allows it to be a cost-savings alternative to lapis lazuli, the more popular stone that dumortierite is often confused with along with sodalite.
This stone has a rich mix of deep navy blue to light blue patterns that look like branches, bands, or speckles with white to rust-colored brown inclusions.
