Obsidian Rock Specimen with White Inclusions - Natural Volcanic Glass #194261 (License: Personal Use)

This high-quality obsidian specimen displays a lustrous, jet-black surface punctuated by intricate white streaks and bands, likely formed from feldspar or cristobalite trapped during rapid cooling of felsic lava. Its conchoidal fracture and vitreous luster highlight its volcanic origin and amorphous silica structure. The irregular shape and polished facets suggest it has been carefully prepared for display or study.

Used in educational geology resources, museum exhibits, mineral collector sites, and spiritual/metaphysical product pages; targets users searching for volcanic rocks, obsidian properties, or decorative specimens.
