This is the first time I post on the forum & I'm looking to get opinions, suggestions, etc. on this bracelet which was my mother's. It's a 7 1/2" L 925 sterling silver bracelet with rectangular jade stones & detailed patterns on the silver which to be honest, I don't know what they are! I can make out what appears to be a rabbit or deer & a person but I could be wrong. The clasp has a lock mechanism as well which is pretty neat! Any idea where it was made? Is it vintage? Is cleaning it a good idea? Thank you in advance for any input.
