AI Appraisal Report

Obsidian is a naturally occurring volcanic glass, usually formed by the rapid cooling of lava. The presence of the white streak can indicate a unique color variation which may enhance its appeal. While common obsidian pieces are typically valued modestly, unique formations or artistic polish may increase value. Given its size and appearance, the estimated range reflects typical retail values for polished specimens.
