Physical properties
Hardness 7 (quartz), white to translucent with black needle-like inclusions, vitreous luster.
Formation & geological history
Formed in hydrothermal veins and pegmatites where silica-rich fluids cool and crystallize alongside tourmaline minerals.
Uses & applications
Often used in lapidary arts, metaphysical practices, and as collector specimens.
Geological facts
Also known as Tourmalinated Quartz, the contrasting black and white appearance makes it a popular decorative stone.
Field identification & locations
Identify by the clear/milky quartz base with distinct dark rod-like inclusions. Found in Brazil, Madagascar, and various pegmatite locations worldwide.
