Artisan made lampwork glass bead necklace in white, fine black lines and 23k gold

I have created three lampwork glass beads that have a white base with fine deep black lines that encircle the surface. There are islands of 23k Italian gold that I have fire-sealed to the beads. An elegant look on the black snake chain necklace. Enjoy, Michael
