You do not say how large it is, so I cant take a guess what it is. But the markings are of course "Sterling" silver, made in "Peru" by the maker "Colmenares" The unknown mark is a 9. Making it "925" for the silver content .925-1000 "A'MANO" by hand.
So, sterling silver made in Peru, by hand by a smith named Colmenares.
p.s. very good looking piece.
