This is the pendant I wrapped with dead soft copper wire and which will be going on my market table tomorrow morning. No idea what the stone is. Reminds me of snowflake obsidian, but this doesn't have the opacity, and it's dyed. Most of the beads on the table in the above picture will end up wrapped. You can get some really cool examples of beads on multi-strings for next to nothing. I got mine from Arton in Toronto a year or two ago.
Thanks for looking!
