Dumortierite is an aluminum boro-silicate mineral that often forms as fibrous aggregations. The crystals are typically blue, however grey-blue, green, and brown crystals are also common. In rare cases, the crystals can be violet or pink. Dumortierite is often found as fibrous crystals within massive quartz: blue dumortierite-included quartz, known as "dumortierite quartz" crystals, are highly sought after.
