Faceted clear gemstone, likely glass imitation or cubic zirconia

Uncertain; possibilities include cubic zirconia (zirconium dioxide, ZrO₂), quartz (SiO₂), or lead glass

AI-generated identification · may be incorrect

Colorless and transparent with strong surface reflections and brilliant faceting. Apparent hardness is indeterminate from the image: cubic zirconia is Mohs 8–8.5, quartz 7, and glass about 5–6; crystal structure cannot be confirmed visually.

Common name: Faceted clear gemstone, likely glass imitation or cubic zirconia
Scientific name: Uncertain; possibilities include cubic zirconia (zirconium dioxide, ZrO₂), quartz (SiO₂), or lead glass
Category: gemstone
Identified: September 16, 2026
Method: Standard

AI Estimated Value

About $1–$50 if glass or common cubic zirconia; $10–$200 if a good cut quartz; substantially more only if confirmed as a natural diamond or other valuable gem.

Physical properties

Formation & geological history

The faceted shape indicates human cutting rather than a natural crystal form. Cubic zirconia is laboratory-grown, while quartz may be natural and later cut; the photograph does not establish geological age.

Uses & applications

Used as costume or fashion jewelry and as a diamond simulant; quartz is also used in jewelry and industry. Construction uses do not apply to a cut stone.

Geological facts

The intense central glare obscures diagnostic features such as doubling, inclusions, facet junctions, and dispersion. It does not appear possible to verify diamond from this image alone.

Field identification & locations

Check with a loupe for inclusions, inspect facet edges, test thermal/electrical conductivity, and measure specific gravity; a gemologist should perform identification. Avoid scratch tests on a finished stone.
