Blue Quartz

    Quartz is the second most abundant mineral in Earth’s crust after feldspar. Blue quartz is opaque to translucent, blue variety of quartz, owing its color to inclusions, commonly of fibrous magnesio riebeckite, crocidolite, or tourmaline. Therefore, the color of included minerals may cause the blue tint.
