I special ordered 16" strands of these high quality 10mm smooth round black agate gemstone beads. A couple beads may be drilled slightly off center, or you may find a bead significantly smaller than the rest. But overall these are near perfect strands with consistent size, great drilling, and excellent polish.
Black agate is also called black onyx, but they are both made by dying gray agates using sugar and sulphuric acid. The dye is stable. If you'd like a naturally black bead, check out black tourmaline.
