Faceted colorless gemstone, likely quartz or glass imitation

Most likely quartz (SiO₂), though the strong glare and visible facet pattern could indicate cubic zirconia or lead glass

AI-generated identification · may be incorrect

Colorless, transparent, vitreous luster, faceted with brilliant-cut geometry; quartz hardness 7, specific gravity 2.65, trigonal crystal structure, with no obvious cleavage. Identification is uncertain because no rough crystal form, inclusions, or scale is visible.

Category: gemstone
Identified: September 14, 2026
Method: Standard

AI Estimated Value

About $1-$20 if ordinary quartz or glass; $10-$100 for a well-cut quartz gem; potentially $20-$300+ if confirmed as quality cubic zirconia or another valuable gemstone.

Physical properties

Formation & geological history

Natural quartz forms in hydrothermal veins and igneous cavities, commonly from the Precambrian onward; cubic zirconia and glass alternatives are human-made. A cut specimen cannot be age-dated visually.

Uses & applications

Quartz is used in jewelry, optics, electronics, and abrasives; cubic zirconia is primarily a diamond simulant. Value depends heavily on confirmed identity, clarity, cut, and weight.

Geological facts

The star-like flashes are reflections from pavilion facets and the camera light, not necessarily asterism. Quartz has lower brilliance and dispersion than diamond or cubic zirconia.

Field identification & locations

Test hardness cautiously: quartz scratches ordinary glass, while glass may not; a gemological refractometer, polariscope, specific-gravity test, and loupe are needed for reliable identification. Common natural quartz sources include Brazil, Madagascar, and Arkansas.
