Sterling silver and snowflake obsidian. MMmmmm. My next door neighbour asked me to look out for something in black and grey when I went to the beadshop last time - to wear to a do she was going to. Unfortunately I took too long as I was ill for a week.
I call it Storm. Because the silver reminds me of lightning and the snowflake obsidian of thunderclouds. Also when I was making there was an almighty hammering noise interspersed with flashes of silver. I felt a bit like Thor (creating a noise rather than being God-like, unfortunately).
