Black Ray-Ban square glasses with blue case

I lost my black Ray-Ban square glasses yesterday around 3pm near the Library of Birmingham on Centenary Square. They're black metal frames with square lenses, a tiny scratch on the upper-right corner, and the inside of the right temple is engraved with the initials 'JS.' They come with a blue hard-shell case with a white 'RB' logo. The loss means a lot to me — I rely on them for work and reading, and they have sentimental value because they were a gift from my grandmother. If anyone found them, please get in touch; I’d be so grateful to get them back.
