Question about symbols

[JReev]

I am trying to find it what a symbol means and can't find anything based off the images. Also trying to find it if the necklace and locket is an older piece or not. Took it somewhere the guy barley glanced at it. The symbol is stamped
and also has 925 and Italy. Any info would be great
