14k yellow gold diamond ring with engraving

I lost my 14k yellow gold diamond ring yesterday around 3pm near the Mall del Norte parking lot off Bob Bullock Loop in Laredo, Texas. It’s a slim solitaire with a tiny 0.25-carat diamond on a narrow, slightly worn band. There’s an engraving inside the band—PK—that can help identify it. The ring is a little bent and has a few scratches from daily wear, but the diamond still catches the light. This ring was a gift from my grandmother, and it means the world to me; I’d really appreciate getting it back if you’ve seen it.
