Cut colorless gemstone, likely quartz or glass imitation

Most plausibly rock crystal (clear quartz, SiO₂); synthetic glass cannot be ruled out from the image

AI-generated identification · may be incorrect

Colorless, transparent, strongly vitreous luster, faceted round brilliant cut, no visible natural crystal faces or inclusions. Quartz hardness is Mohs 7, specific gravity 2.65, and trigonal; glass is typically Mohs 5–6 and lacks crystal structure.

AI Estimated Value

About $1–$30 if glass or common imitation; $5–$100 for ordinary faceted quartz, depending on size, clarity, and workmanship.

Physical properties

Formation & geological history

Natural quartz forms in hydrothermal veins and igneous cavities, commonly from Paleozoic to younger geological settings; the photographed faceted object has been cut and polished. If glass, it is manufactured rather than geological.

Uses & applications

Quartz is used in jewelry, optics, electronics, and ornamental items; faceted quartz is an inexpensive gemstone. Glass imitations are mainly decorative.

Geological facts

The round brilliant faceting and very uniform appearance suggest a manufactured gem, possibly quartz, cubic zirconia, or glass. A photograph cannot reliably separate these materials.

Field identification & locations

Check with a loupe for inclusions, test hardness cautiously, and measure refractive index or specific gravity for identification; quartz will not scratch with a steel blade but can scratch ordinary glass. Common quartz sources include Brazil, Madagascar, and the United States.
