These Black Obsidian “spheres” are glossy, deep-black volcanic glass pieces with a natural mix of sheen—most show flashes of golden or silvery shimmer in the light, while a few may appear more solid black with little to no sheen. They are not perfectly round, matched spheres; think of them as larger rounded tumbles in assorted sizes, ranging from oval to near-round, each with its own unique shape and character.
