Diamond (carbon, C); identification cannot be confirmed from the image

AI-generated identification · may be incorrect

Colorless, transparent, brilliant faceted stone in a metal pendant setting; diamond has Mohs hardness 10 and a cubic crystal structure. Faceting and reflections alone cannot distinguish diamond from glass or cubic zirconia.

AI Estimated Value

Not reliably estimable from the image: if diamond, value may range from tens to thousands of USD depending on identity, weight, cut, clarity, and setting; simulants are usually much less.

Not an official valuation

AI estimate for general interest only — not an appraisal. Actual value depends on condition, provenance, and market demand. Verify with a professional before buying, selling, or insuring.

Physical properties

Formation & geological history

If diamond, it formed under high pressure and temperature deep in the mantle and was transported toward the surface in volcanic kimberlite or lamproite; its age depends on the source deposit.

Uses & applications

Jewelry and collecting; diamonds are also used in cutting and abrasives.

Geological facts

The pendant’s small size and setting obscure diagnostic features; reliable identification requires gemological testing, such as thermal conductivity and examination under magnification.

Field identification & locations

A loose stone can be checked for inclusions, facet wear, and optical properties, but visual inspection of this photo is insufficient. Diamonds occur in deposits including Botswana, Russia, Canada, South Africa, and Australia.
