Deep blue Dumortierite quartz, known as the "blue denim stone," is a rare and notable variant of quartz. It is found in Brazil, sometimes self-healed with a phantom rainbow, and takes the form of masses, small prismatic crystals, or as fibrous inclusions within Quartz. Acicular sprays of transparent elongated Dumortierite, flowering tufts surrounding penetrating negative crystals, and grass-like beds of blue needles have been observed.
