Czech seed beads in the shape of a short cut cylinder are called Preciosa Ornela Three-Cut Beads (also known as Preciosa Three-Cuts or Preciosa 3cuts). They are made using a similar technology to Preciosa Two-Cut Beads, i.e. by cutting glass tubes with a round hole and a hexagonal surface. After this process, the PRECIOSA Three-Cut Beads are cut again on special cutting wheels while strung on a wire which results in the reduction of the edges at the ends of the seed beads and the cutting of several randomly placed facets.
Each PRECIOSA Three-Cut Bead has a unique shape. PRECIOSA Three-Cut Beads are made in five basic sizes ranging from 1.6 mm to 2.5 mm (from 12/0 to 8/0 in the zero series).
