Dumortierite is a minor blue gemstone that usually forms as inclusion s in Quartz. Its most common color is blue or grayish-blue, though pink and purple colors are also known. Dumortierite's durability, combined with a high hardness, would make this an ideal gemstone, but the lack of transparency and often dull luster limit its use.
