Faceted yellow-brown gemstone earring

Likely citrine (quartz, SiO₂), though treated quartz or synthetic glass cannot be confirmed from the image

AI-generated identification · may be incorrect

Transparent golden-brown, vitreous luster, faceted cut; quartz hardness is Mohs 7, lacks visible cleavage, and has a trigonal crystal structure. The metal setting and regular facets indicate a finished jewelry specimen.

Physical properties

Formation & geological history

Natural citrine forms when iron-bearing quartz crystallizes in hydrothermal veins or igneous cavities, commonly during granite formation; much commercial citrine is heat-treated amethyst. Geological ages vary widely by deposit.

Uses & applications

Used in jewelry and ornamental objects; the mounted earring has primarily decorative value.

Geological facts

Citrine’s yellow color results from iron-related defects; heated amethyst can produce orange-brown “Madeira” tones. Image-only identification cannot reliably exclude yellow topaz, treated quartz, or glass.

Field identification & locations

Check hardness, inclusions, refractive behavior, and specific gravity; quartz typically scratches glass but not corundum, while glass often shows round gas bubbles. Common sources include Brazil, Uruguay, Madagascar, and Zambia.
