Amethyst and rose-quartz bead jewelry

Amethyst: quartz, SiO₂, purple variety; rose quartz: quartz, SiO₂; possible smoky/clear quartz and other beads

AI-generated identification · may be incorrect

Polished spherical beads with vitreous luster; amethyst is purple, rose quartz pink, and darker beads may be smoky quartz or another stone. Quartz hardness is Mohs 7, trigonal crystal structure, conchoidal fracture, and no cleavage; exact identification of every bead is not possible from the image.

Physical properties

Formation & geological history

Quartz crystallizes from silica-rich hydrothermal fluids and igneous cavities, commonly during late-stage cooling of granitic rocks; rose quartz and amethyst formed in various Precambrian to younger deposits. The beads are human-cut and polished.

Uses & applications

Used primarily in bracelets, meditation items, and inexpensive gemstone jewelry; quartz is also important industrially for glass, electronics, abrasives, and engineered stone.

Geological facts

Amethyst’s purple color is produced mainly by irradiation and trace iron, while rose quartz commonly owes its pink color to microscopic inclusions. Color alone cannot distinguish all dark or translucent beads.

Field identification & locations

Quartz beads feel cool, resist scratching by a steel knife, and show glassy polish; use a loupe for inclusions, but avoid destructive tests on jewelry. Major sources include Brazil, Uruguay, Madagascar, India, and the United States.
