Clear faceted gemstone, likely quartz (rock crystal)

Quartz, silicon dioxide (SiO₂); exact identity cannot be confirmed from the glare-heavy image

AI-generated identification · may be incorrect

Colorless and transparent with brilliant faceting and vitreous luster; quartz has Mohs hardness 7, trigonal crystal structure, no true cleavage, and specific gravity about 2.65. The round brilliant cut and intense reflections indicate a cut stone rather than a natural crystal.

Method: Standard

AI Estimated Value

About $5–$100 for ordinary cut quartz; potentially much higher for confirmed diamond or fine gemstone. Professional testing is necessary before valuation.

Physical properties

Formation & geological history

Natural quartz forms in hydrothermal veins and cavities, commonly from Precambrian to younger rocks; gem material is mined in Brazil, Madagascar, the United States, and elsewhere. Cutting and polishing are human processing, not geological formation.

Uses & applications

Used in jewelry and ornament; lower-grade quartz is important in glass, ceramics, abrasives, and electronics. If actually diamond or synthetic cubic zirconia, its properties and value would differ substantially.

Geological facts

The photograph’s strong flashlight reflection prevents reliable separation of quartz from diamond, cubic zirconia, or glass. Facet pattern and brilliance alone are insufficient for identification.

Field identification & locations

Check hardness, specific gravity, thermal conductivity, and refractive index with a gemologist; avoid scratch tests on valuable stones. Quartz commonly shows inclusions and relatively moderate fire compared with diamond.
