Physical properties
Colorless and transparent with a glassy luster and pointed crystal-like facets. Quartz has Mohs hardness 7, a trigonal crystal structure, no cleavage, and specific gravity about 2.65; the image does not show enough detail to verify the material conclusively.
Formation & geological history
If natural quartz, it formed as silica-rich fluids crystallized in cracks or cavities, across many geological ages. The pendant appears shaped and polished, with a metal fitting.
Uses & applications
Quartz is used in jewelry, glassmaking, electronics, and as an industrial abrasive; this piece is likely decorative jewelry.
Geological facts
Quartz is one of Earth’s most abundant minerals and occurs in many colors and crystal forms.
Field identification & locations
A genuine quartz crystal is relatively hard and lacks cleavage; confirm identity by testing the loose stone, not the pendant. Clear quartz occurs worldwide, including Brazil, Madagascar, and the United States.
