This necklace combines several shades of blue, and the use of opaque and translucent beads provides interesting visual effect. 

The opaque dark blue beads are smooth rounds of blue goldstone, which has its characteristic subtle gold flecking visible throughout.

The paler blue beads are faceted glass. Textured silverplated spacer beads add a bit of pizazz.

The necklace is 18 inches long, is strung on jeweler's wire and has a lobster closure.
