Colorless faceted gemstone, likely quartz (rock crystal)

Quartz, silicon dioxide (SiO₂); exact identification cannot be confirmed from the photograph

AI-generated identification · may be incorrect

Colorless and transparent with strong glassy luster and numerous brilliant-cut facets. Quartz has Mohs hardness 7, hexagonal crystal structure, no cleavage, and specific gravity about 2.65; the unusually intense sparkle may also indicate synthetic glass or cubic zirconia.

AI Estimated Value

About $5–$30 if common faceted quartz; $1–$10 if glass, with substantially higher prices possible for verified fine natural material.

Physical properties

Formation & geological history

Natural quartz forms in hydrothermal veins and igneous cavities, commonly from Paleozoic to younger geological settings; faceting is human processing. Faceted cubic zirconia or glass would be manufactured rather than geologically formed.

Uses & applications

Faceted quartz is used in inexpensive jewelry and collecting; natural quartz also has major electronics and industrial uses. Typical value is low unless exceptionally clear, large, or provenance-rich.

Geological facts

The photograph shows a round brilliant-style cut rather than a natural crystal, and flash obscures diagnostic inclusions and refractive behavior.

Field identification & locations

Test cautiously: quartz scratches ordinary glass, while glass generally does not; quartz also feels less dense than cubic zirconia. Check facet wear, bubbles, inclusions, birefringence, and refractive index with gemological tools; do not rely on appearance alone.
