Physical properties

Hardness: 7 on the Mohs scale. Color: White to translucent matrix with black acicular tourmaline inclusions. Luster: Vitreous to greasy. Crystal System: Trigonal. Cleavage: None.

Formation & geological history

Formed in hydrothermal veins and pegmatites through the crystallization of silica-rich solutions containing trace boron and iron elements over millions of years.

Uses & applications

Used in mineral collecting, lapidary arts, metaphysical practices, and ornamental displays.

Geological facts

Tourmalinated quartz combines the amplifying properties of clear quartz with the protective grounding energy of black tourmaline, making it a popular specimen for crystal enthusiasts.

Field identification & locations

Identifiable by its contrasting white quartz body peppered with dark, needle-like black tourmaline crystals. Commonly found in pegmatite-rich regions worldwide.
