Faceted yellow gemstone ring

Likely yellow sapphire (corundum), but exact identification requires testing; alternatives include citrine, chrysoberyl, or treated diamond.

AI-generated identification · may be incorrect

The stone is transparent, yellow-brown, faceted, and vitreous; apparent round brilliant cut with moderate inclusions. Yellow sapphire is Mohs 9, hexagonal/trigonal corundum, with no cleavage and specific gravity about 4.0.

AI Estimated Value

Approximately $20–$150 if synthetic or imitation, $100–$1,000 for commercial yellow sapphire, and potentially $1,000–$10,000+ for fine untreated stones; the complete ring depends on metal and certification.

Physical properties

Formation & geological history

If sapphire, it formed in aluminum-rich metamorphic or igneous environments, commonly millions to billions of years old; gemstones are later cut and mounted in metal. A photograph cannot establish composition or geological age.

Uses & applications

Used primarily in jewelry; sapphire is durable for rings, while citrine is less scratch-resistant. The setting appears to be gold-colored metal, but its purity cannot be determined visually.

Geological facts

Color and faceting alone are insufficient for identification, and apparent inclusions may indicate a natural stone, treated material, or glass imitation. Refractometer, polariscope, specific-gravity, and microscope testing are appropriate.

Field identification & locations

Inspect for natural inclusions, check hardness professionally, and avoid destructive scratch tests; a jeweler or gemologist can confirm identity and treatments. Yellow sapphires occur in Sri Lanka, Madagascar, Myanmar, Tanzania, and Australia.
