Clear faceted gemstone in a gold-colored setting

Likely colorless quartz (rock crystal) or synthetic cubic zirconia; visual identification is inconclusive

AI-generated identification · may be incorrect

Colorless, transparent, strongly vitreous and faceted, apparently mounted in metal. Quartz has Mohs hardness 7 and hexagonal crystal structure; cubic zirconia has hardness about 8–8.5 and cubic structure. The surrounding yellow metal may be gold alloy or plated base metal.

AI Estimated Value

About $5–$50 if quartz or cubic zirconia in costume jewelry; roughly $50–$300+ if confirmed natural quartz with valuable metalwork; appraisal is required.

Physical properties

Formation & geological history

If quartz, it formed from silica-rich hydrothermal fluids, commonly in cavities and veins; if cubic zirconia, it is laboratory-grown and not geological. Geological quartz may range from Precambrian to recent deposits.

Uses & applications

Used as a jewelry stone, ornamental centerpiece, or costume-jewelry substitute. Quartz is common and durable; cubic zirconia is valued for diamond-like brilliance at low cost.

Geological facts

The bright flashes and apparent round brilliant cut suggest a faceted stone rather than a natural crystal. A loupe, refractive-index test, and specific-gravity measurement are needed for reliable identification.

Field identification & locations

Check for inclusions, doubling of facet edges, facet wear, and bubbles; quartz scratches glass, while glass does not scratch quartz. Common natural sources include Brazil, Madagascar, and the United States.
