Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent white quartz with distinct black schorl tourmaline needles, vitreous luster, and conchoidal fracture.
Formation & geological history
Formed through hydrothermal processes where quartz crystals grow around pre-existing tourmaline crystals deep within pegmatite veins.
Uses & applications
Used primarily in lapidary arts, metaphysical healing, jewelry making, and as a popular display specimen for mineral collectors.
Geological facts
The contrasting black and white pattern makes it a favorite for custom carvings and minimalist jewelry designs. It symbolizes the balancing of polar energies.
