Heart chain bracelet

Used heart chain bracelet. has some scratches. some silver peeled off in the interior of heart where the chain holds heart in pic 5. i tried to capture the peeled off siver areas in pics 4, 6 and 7 but very difficult to show since it shows the reflection of my phone. shows signs of normal wear but in good condition and has a lot of life left. not sure of the material. questions?, please ask!
