Physical properties

Transparent, glassy luster with large polished facets; quartz has Mohs hardness 7 and a trigonal crystal structure, but this appears cut rather than naturally crystal-faced.

Formation & geological history

If quartz, it formed from silica-rich fluids or magma in geological settings over a range of ages; the displayed object is extensively cut and polished.

Uses & applications

Faceted quartz is used in jewelry and ornamental displays; a monumental piece may be primarily decorative.

Geological facts

Its unusually large, geometric facets suggest a crafted display object, not an uncut natural crystal.

Field identification & locations

Colorless quartz is commonly found worldwide, including in veins and pegmatites. Confirm identity through gemological testing, since clear glass or another transparent material can look similar in a photo.
