Yellow faceted gemstone, likely citrine or yellow sapphire

Uncertain; probable quartz (SiO₂) or corundum (Al₂O₃)

AI-generated identification · may be incorrect

A small transparent-to-translucent yellow faceted stone in a metal ring. Apparent vitreous luster and cut facets are visible, but color, inclusions, and setting prevent reliable separation of citrine from sapphire or treated glass. Quartz hardness 7; sapphire hardness 9; specific gravity about 2.65 versus 4.0.

AI Estimated Value

About $5–$50 if glass or synthetic; $20–$150 for ordinary citrine; roughly $100–$2,000+ for natural yellow sapphire depending strongly on treatment, clarity, size, and certification.

Physical properties

Formation & geological history

If citrine, it formed in silica-rich igneous or hydrothermal environments, commonly as heat-treated amethyst. If sapphire, it formed in aluminum-rich metamorphic or igneous rocks. The image cannot establish geological age or whether the stone is synthetic or treated.

Uses & applications

Used primarily in jewelry. Citrine is common and relatively inexpensive; natural yellow sapphire is substantially more valuable, while synthetic or glass imitations are inexpensive.

Geological facts

The surrounding ring is human-made, but the central stone may be geological material. Faceting alone does not prove natural origin; laboratory testing is required.

Field identification & locations

The reported Bihar location is more consistent with an imported or traded gemstone than a locally formed sapphire or citrine. Check refractive index, specific gravity, hardness, and inclusions with a gemologist; do not scratch it if identification matters.
