Physical properties

Formation & geological history

Quartz gemstones form in silica-rich hydrothermal veins and volcanic cavities, commonly during late-stage cooling of igneous systems. Geological ages vary widely depending on the deposit; the bracelet is human-assembled and polished.

Uses & applications

Used as personal jewelry, ornament, and a lapidary collectible; amethyst is also used decoratively and traditionally in metaphysical products. Commercial value is usually modest unless beads are unusually fine or the bracelet contains certified precious material.

Geological facts

Amethyst’s purple color results mainly from iron impurities and irradiation. Heat treatment can turn amethyst yellow or orange, producing citrine-like material.

Field identification & locations

Identify amethyst by purple color, glassy luster, hardness, and lack of bubbles; natural stones commonly show color zoning or inclusions. Major sources include Brazil, Uruguay, Zambia, and Bolivia; mixed beads cannot be identified confidently from the image alone.
