What is Dumortierite?
Dumortierite is a striking crystal best known for its deep blue colour, though it can also appear in shades of purple, brown, or even green. Named after the French palaeontologist Eugène Dumortier, this stone is valued both for its aesthetic appeal and its reputed metaphysical properties.
