This premium black and white Dzi bead features an exceptionally rich, oily texture and beautifully aged coloration. The black and white hues are sharply contrasted and vividly distinct. Completely opaque under strong light, the bead is hand-polished from naturally weathered old stock material, retaining an organic, freeform shape. The surface displays full, fine matte-finish weathering marks and delicate drag marks (拉丝痕), indicative of age and hand craftsmanship. The patina is thick, smooth, and full-bodied. Dimensions: 11.3 mm × 17 mm.
