don't think there were tennis bracelets in victorian times?
you need to show a good clear close-up because we can't tell if there are diamonds or it is just laser cut. your potential buyers won't be able to tell either.
The clasp is modern. Can't see if it was attached later to the bracelet but doesn't look like it. It isn't Victorian, Edwardian, Nouveau or Deco. Not even vintage.
