Quartz (SiO₂), possibly smoky quartz; identification from the photo is uncertain

AI-generated identification · may be incorrect

The rectangular step-cut stone is translucent brown with a vitreous luster, consistent with quartz (Mohs 7; trigonal crystal structure, no cleavage). The metal setting and surrounding accents cannot be identified reliably from the image.

Physical properties

Formation & geological history

If smoky quartz, its color comes from natural irradiation of trace aluminum in quartz, commonly in granitic pegmatites and hydrothermal veins; quartz formed in many geological periods.

Uses & applications

Cut quartz is used in jewelry and ornamental objects; the ring’s value depends on the confirmed stone, metal, workmanship, and any accent stones.

Geological facts

Brown faceted stones can also be citrine, topaz, or glass, so appearance alone cannot establish the gem species.

Field identification & locations

A jeweler or gemologist can distinguish candidates using refractive index, inclusions, and other gem tests; the photo does not reveal diagnostic features or locality.
