It's the Batwax! Ok, really, I just couldn't come up with a better name for it. This is getting cast this week. I'm thinking this will be a one of a kind necklace - I'll solder chain to it at the very end. Getting it light enough has been interesting...it probably could still be lighter, but I'll deal with that when I start cleaning up the metal.
The stone is a cushion-cut checkerboard top citrine. I think it will work well. I may incorporate another stone or two, but haven't decided yet. Sometimes it's nice to make things up as you go.
