Blue king-size duvet cover with white piping

I lost my blue king-size duvet cover yesterday around 3pm near the Starbucks on High Street by the North Market in Columbus. It's a bright blue 100% cotton cover with white piping along all edges, and there's a tiny snag in the left corner plus a faint coffee stain on the inside seam. It has sentimental value - my grandmother gave me this set - and I really need it back. If you found it, please reach out here so we can arrange a quick return.
