Large Natural Obsidian Specimen - Volcanic Glass With Conchoidal Fracture

Offered is a substantial natural obsidian specimen, a volcanic glass formed by the rapid cooling of silica-rich lava. The piece displays a deep black, glossy surface with pronounced conchoidal (shell-like) fracture patterns and sharp, angular edges characteristic of obsidian. Scattered natural inclusions and surface variations are present, consistent with a raw, unpolished geological specimen.
Size approx. 4.75" x 4".
This is a visually striking example, well suited for mineral collectors, educational displays, lapidary interest, or decorative use.
