Genuine sterling silver ring

Beautiful genuine (stamped 925) sterling silver ring. Has been worn quite a few times and does show some scratches from wear. Has a beautiful large center stone (1ct? Maybe 1.5ct) with 2 smaller stones on the sides. I think these are cubic zircon but could be sapphire I'm not sure. Either way this is a beautiful ring that has beautiful shine! Size is about 6 or 7.
