Sheen Obsidian Sphere

The Sheen Obsidian spheres are polished volcanic glass pieces that display subtle metallic sheen caused by tiny mineral inclusions formed during rapid cooling of lava. Shaped into smooth spheres about 1 inch in diameter, they allow the surface sheen to catch the light from multiple angles, making them especially engaging for close observation. These pieces are well suited for geology students, collectors, and anyone interested in volcanic processes and igneous rocks.
