Okay, so really it's "Angel with the Turquoise Dress," but blue dress sounds better.
This piece... took... a very long time. Especially because the angel is actually hand-made as well... hand-picked beads and all. This set was made for a very close friend of mine (who, obviously, is a little on the religious side, thus the angel theme). There are a total of 3 strands strung together in this piece. The beads featured are turquoise, of course, and a large variety of glass seed-beads. It's a pretty chunky looking necklace but it looks fabulous, I'm very proud of this piece.
A necklace like this would cost you in the $50 range because it is very labor-intensive. I can probably make something like it (with another pendant or no pendant) with almost any semi-precious stone.
The necklace/earring set would cost you more like $65.
