Obsidian is a naturally occurring volcanic glass formed when lava cools rapidly, typically appearing black with a smooth, glass-like surface and no visible crystal structure.
It forms during rapid cooling of silica-rich lava and has been used historically for cutting tools and blades due to its ability to fracture into extremely sharp edges.
This specimen features a deep black tone with a smooth, reflective surface that reads more like glass than stone.
The surface appears continuous and non-crystalline, with subtle variation in reflectivity rather than visible crystal points or texture.
The uniform dark color combined with the glossy finish creates a clean, high-contrast look that stands apart from more textured or multi-toned minerals.
