Possible tektite (natural impact glass)

Impact glass; exact type uncertain from photograph (candidate: moldavite or another tektite)

AI-generated identification · may be incorrect

Dark brown to olive, translucent at thin edges, glassy luster, and irregular sculpted surfaces. Tektite glass has no crystal structure or cleavage and is typically about 5–7 Mohs; density and identity cannot be confirmed visually.

Physical properties

Formation & geological history

Tektites form when a meteorite impact melts terrestrial material and ejects it, which cools into glass. If this is moldavite, it formed about 14.8 million years ago during the Ries impact in central Europe; the image alone cannot establish that identification.

Uses & applications

Tektites are collected and sometimes used in jewelry; verify authenticity before purchase, as imitation glass is common.

Geological facts

The pointed, flow-like shape and glassy appearance suggest impact glass, but lighting and scale make visual identification uncertain.

Field identification & locations

Look for natural pitted or sculpted surfaces, glassy edges, and consistent material throughout; a gemological or laboratory test is needed. The reported Tehran-area location does not match moldavite’s restricted central-European source, so a local rock or glass-like mineral is a plausible alternative.
