Dark quartz point (possibly smoky quartz)

Quartz, SiO₂; the dark color may indicate smoky quartz, but the image is insufficient to confirm

AI-generated identification · may be incorrect

A polished, pointed crystal with dark gray-brown color and vitreous luster. Quartz has Mohs hardness 7, a hexagonal crystal structure, and no cleavage; the specimen’s translucency and precise identity cannot be determined from the image.

Physical properties

Formation & geological history

Quartz crystallizes from silica-rich fluids in veins and cavities, or from cooling magma; smoky coloration commonly develops through natural irradiation. Quartz occurs in rocks of many geological ages.

Uses & applications

Quartz points are commonly collected or used as decorative objects; quartz also has major industrial uses in glass, electronics, and abrasives.

Geological facts

The pointed shape appears shaped or polished rather than a complete natural crystal termination; it may be a carved point made from quartz or another dark stone.

Field identification & locations

Check hardness and streak, and inspect for quartz’s glassy luster and conchoidal fracture; visual identification alone is uncertain. Quartz is widespread worldwide.
