We've had this fella for last 20yrs and he was secondhand then so it's time I found out where he emigrated from. I always thought he might be french. He's 5" long X2 1/2" high and very heavy. He's a very opaque black, no agate about him ( I read the discussion on black glass, thanks) if he is amethyst its very dense. Any help much appreciated. steph.
