Mahogany obsidian beads, donuts and gemstone pendants offer you lovely semiprecious beads in deep shades of reddish-brown with attractive black speckles.
Obsidian (pronounced ub-SIH-dee-in) is a natural glass that forms from volcanic activity. As a result, obsidian beads are somewhat fragile.
They are slightly harder than window glass, but can scratch easily and sharp blows can crack them, so treat obsidian jewelry components with care.
