White lined stone drop statement necklace in silver or silvertone

Pretty stones set up like flower buds with the silvertone leaves below them. I am not positive that this piece is not real silver since the stones seem authentic but I'm not positive about that either so I'm going to price neutral. Either way The stones do look & feel authentic. The clasp of the necklace looks like it is stamped & authentic however the chain might be silvertone. It's a beautiful piece whatever it might be. stones are 3/4" L x over 1/2" W though much larger in their detailed silvertoned frames. The chain is a circle link & measures up to 26" New
