I have this sterling and abalone brooch that I'm having trouble finding the maker. I thought he looked rather unique. Does this look like anyones work? I was only able to get the sterling and 925 on the back. Most of everything else has be cut off. Any help is greatly appreciated.

Can't see the mark clear enough to make out anything. The piece is shown upside down, looks like cactus.
BTW, your picture link tried to download something on my PC, not a safe link.
