A Pimps ring

Found this baby in a unit I bought this week. It is marked 18K and the big stone looks to be Aquamarine. It seems to big for a women so I figure a pimp.
The unit appears to have belonged to a hoarder who was homeless. I think all the stuff in it was stuff he found  on the street lots of well worn knives and junk.  I should make money on it but this ring really helps as does the Omega Seamaster in poor shape but running.

big pimpin!
