Gold 14k solitaire diamond ring with initials

I lost my gold 14k solitaire diamond ring yesterday around 3pm near the Pearl Street Mall, outside the Boulder Book Store on Pearl Street. It's a slim 2mm band with a tiny round diamond that still shines in the sun, and the inside is engraved with the initials 'RP'. The ring means a lot to me — it was a gift from my grandmother and carries real sentimental value. I’ve retraced my steps along the Pearl Street Mall and the Boulder Creek Path, but I must have dropped it somewhere between the storefronts and the bus stop. If anyone found it, I’d really appreciate getting it back.
