both pieces are stamped 925... the necklace clap though was changed to a magnet. .it was easier to put on and off that way... you can see where the price sticker was on the back but that would easily come off... this is a vintage piece that my grandma had forever...it's in excellent condition... the silver is nice and thick pendant is roughly 3" in length... maybe a little bigger. If you need an exact measurement please let me know 🙂 please check out all the pictures and message me with any questions you might have before purchase... thanks a bunch!🥰
