Silver-tone earrings with clear stones

I lost my silver-tone stud earrings yesterday around 3pm. They’re small, about half a centimeter, with clear cubic zirconia stones and the backs have a tiny scratch on the clasp. I was walking near the Capitol Center for the Arts on North Main Street in Concord, NH, around that time, and I fear they slipped out somewhere between the sidewalk and the coffee shop by the State House. They were a gift from my grandmother and hold sentimental value, so I’d really appreciate getting them back. If you found one or both, please let me know — I can point out the tiny back scratch and the slightly brighter sparkle on one stone to help confirm ownership.
