White gold ring with sapphire centerpiece

I lost my white gold ring yesterday around 3pm near the Phoenix Suns Arena, right outside the CityScape area on 1st Street and Jefferson. It's a size 6, 14k white gold band with a single oval sapphire bezel-set in the center. The ring is simple but meaningful: there’s a tiny, almost invisible engraving on the inside that reads 'M+L', and the bezel has a small, barely noticeable nick on the left edge from a hallway fall. It was a gift from my grandmother and carries a lot of sentimental value, so I’m really hoping it turns up. If you’ve seen it, please let me know—thank you.
