This was made from a striking Double Helix glass and has been encased in clear. It has fabulous colors spilling over the surface in red, burgundy, mauve and yellow. This bead has also been cored with sterling silver and I've also used some fabulous sterling silver bead caps.
This is a 13(including core and bead caps) x 16mm bead with a 4.37mm bead hole.
Bracelet shown not included. The last picture is just to show you how my beads look on a bracelet.
