When Coolmoon suggested varicite I thought we had it! I was all psyched....looked at lots of images of varicite and gee.....I'm not sure. It would make sense that it's varicite as so much is found locally (I'm in Utah) but I just don't see the graininess. Thanks Coolmoon...but I don't think we're there yet. I have stopped working on the necklace as I want to see if I can find some matching beads when we're in Vegas on Monday....you know, you get an idea as you're working on something and it makes you change the design.
