AI-generated identification · may be incorrect

The large faceted, brown-olive transparent stone is consistent with smoky quartz or heat-treated/color-treated quartz. Quartz has Mohs hardness 7, vitreous luster, and a trigonal crystal structure; the ring setting obscures diagnostic features.

Physical properties

Formation & geological history

Quartz forms in igneous and hydrothermal environments and in metamorphic rocks; its age depends on the deposit. The mounted, cut stone’s source and treatment are not identifiable from the image.

Uses & applications

Faceted quartz is used in jewelry and as a collectible gemstone; quartz also has extensive industrial uses in glass and electronics.

Geological facts

Brown quartz color can arise from natural irradiation or treatment, and appearance alone cannot reliably distinguish smoky quartz from other brown gemstones or glass.

Field identification & locations

Check with a gemologist or refractive-index testing to identify it confidently; quartz is common worldwide, including Brazil, Madagascar, and the United States.
