Pressed Czech Glass Silky Beads, made in the Czech Republic, are distinguished by their two diagonally-drilled holes that create a beautiful, diamond-shaped bead. You will notice that one side has a ridge while the other side is simply flat. Together, these features really make Silky Beads stand out as unique. Silky beads feature two diagonal holes which enables then to be strung in a nested diamond pattern by simply alternating the top and bottom holes.
