Faceted transparent gemstone pendant

Uncertain from image; likely faceted quartz (SiO₂), cubic zirconia (ZrO₂), or glass imitation

AI-generated identification · may be incorrect

Colorless to champagne-toned, transparent, high brilliance, faceted cut, and mounted in metal; hardness cannot be determined visually. Natural quartz is Mohs 7 with vitreous luster and hexagonal crystals, while cubic zirconia is Mohs 8–8.5 and typically more fiery.

Physical properties

Colorless to champagne-toned, transparent, high brilliance, faceted cut, and mounted in metal; hardness cannot be determined visually. Natural quartz is Mohs 7 with vitreous luster and hexagonal crystals, while cubic zirconia is Mohs 8–8.5 and typically more fiery.

Formation & geological history

If quartz, it formed in hydrothermal veins or cavities over geologic time; if cubic zirconia, it is laboratory-grown and not geological. The pendant setting and chain are human-made.

Uses & applications

Jewelry and ornament; value depends on confirmed identity, carat weight, clarity, cut, metal, and provenance.

Geological facts

The photograph does not show diagnostic inclusions or crystal structure, so a reliable gemstone identification is impossible. A jeweler can distinguish quartz, zircon, cubic zirconia, and glass using refractive index and specific-gravity tests.

Field identification & locations

Inspect under magnification for bubbles (glass), natural inclusions, and facet quality; avoid scratch testing a finished jewel. Common quartz sources include Brazil, Madagascar, and the United States.
