Faceted clear gemstone, likely quartz or glass imitation

Most likely quartz (SiO₂); exact identification requires refractive-index and hardness tests

AI-generated identification · may be incorrect

Colorless to pale gray, transparent, vitreous luster, brilliant faceting, and no visible natural inclusions. Quartz hardness is Mohs 7, specific gravity 2.65, and it has hexagonal crystal structure with poor cleavage; the photograph cannot exclude man-made glass or cubic zirconia.

Common name: Faceted clear gemstone, likely quartz or glass imitation
Scientific name: Most likely quartz (SiO₂); exact identification requires refractive-index and hardness tests
Category: gemstone
Identified: September 14, 2026
Method: Standard

AI Estimated Value

About $5–$50 if quartz; $1–$20 if glass; $20–$200+ if a larger, high-quality confirmed gemstone. Identification from this image alone is uncertain.

Physical properties

Formation & geological history

Natural quartz forms in hydrothermal veins and igneous cavities, commonly from Paleozoic to recent geological settings; a cut specimen may have been fashioned from much older material. If glass or cubic zirconia, it is entirely synthetic.

Uses & applications

Used as a jewelry stone, ornament, or optical specimen; quartz is also important in electronics and industry. Faceted quality depends on clarity, cut, and confirmed identity.

Geological facts

Strong flashes are caused by facet reflections and do not prove diamond. A loupe, polariscope, refractometer, and thermal-conductivity tester can separate quartz from common imitations.

Field identification & locations

Check for facet junction quality, inclusions, bubbles, scratches, and doubling of rear facets; quartz scratches ordinary glass but not corundum. Common natural sources include Brazil, Madagascar, the United States, and the Alps.
