Faceted yellow-brown gemstone ring

Likely citrine (quartz, SiO₂); the image alone cannot confirm the stone or any treatments.

AI-generated identification · may be incorrect

The large faceted stone appears transparent yellow to brown with a vitreous luster; quartz has Mohs hardness 7 and a trigonal crystal structure. The surrounding setting appears to be metal with small accent stones.

AI Estimated Value

The ring’s value cannot be reliably estimated from the image; loose citrine is often about $5–$100 per carat, while setting, stone identity, and quality strongly affect total value.

Physical properties

Formation & geological history

If citrine, it formed as quartz in silica-rich hydrothermal veins or pegmatites; commercial material is commonly heat-treated amethyst. Quartz deposits span many geological ages.

Uses & applications

Citrine is used in jewelry and collected as a colorful, relatively durable gemstone.

Geological facts

Yellow-brown appearance can also occur in other gems or glass, so visual identification is uncertain; gemological testing is needed to establish identity and treatment.

Field identification & locations

Check refractive index, inclusions, hardness, and spectroscopy with a gemologist; common citrine sources include Brazil, Madagascar, and Uruguay. The image does not show enough detail to verify the stone.
