Tourmaline Quartz Donut Pendant measuring 3 cm
Tourmaline quartz
Tourmaline quartz is a variety of quartz that contains black needle-like inclusions of tourmaline (usually schörl). The contrast between the clear or milky quartz and the darker tourmaline needles gives the stone a distinctive and unique appearance. This makes each piece different and popular in both jewellery and collectibles.
Major deposits of tourmaline quartz include Brazil, Madagascar, Pakistan and the United States. The mineral is formed when quartz and tourmaline crystallise simultaneously in pegmatites or hydrothermal veins. The chemical formula of the quartz is SiOâ‚‚, combined with inclusions of tourmaline, and its hardness is 7 on the Mohs scale.
