Most, but not all, of these 10mm round black obsidian beads have golden schiller inclusions. Well drilled with an excellent polish that really makes these beads shine.
Obsidian is not classified as a mineral because it lacks a crystalline structure. It is a volcanic glass that is formed from rapid cooling of volcanic lava.
