Carved amethyst fluorite (likely)

Amethyst, purple variety of quartz (SiO₂), possibly with fluorite (CaF₂)

AI-generated identification · may be incorrect

A polished, carved purple-and-lavender specimen with translucent zones and a tan-brown area; the image alone cannot confirm whether it is quartz, fluorite, or a combination. Amethyst is Mohs 7, vitreous, and trigonal; fluorite is Mohs 4, vitreous, and cubic, with perfect cleavage.

Physical properties

Formation & geological history

Amethyst forms when silica-rich fluids deposit quartz in cavities, commonly in volcanic rocks; fluorite forms from mineral-rich hydrothermal fluids. Such deposits range in age from ancient to geologically recent.

Uses & applications

Primarily carving, jewelry, and collecting; amethyst is also used as an ornamental gemstone, while fluorite has industrial uses as a flux and source of fluorine.

Geological facts

Purple color in amethyst is associated with trace iron and natural irradiation. Carving and polishing do not make a geological specimen non-natural.

Field identification & locations

Purple translucence is consistent with amethyst, but fluorite can look similar and is softer; a hardness or mineralogical test is needed for certainty. Amethyst is widely found in Brazil, Uruguay, and elsewhere; small carved pieces commonly sell for about $10–$50 USD.
