Gold signet ring with initials inside

I lost my gold signet ring yesterday around 3pm near Cardiff Central Library on The Hayes. It's a slim 9k gold band with a tiny 'LJ' engraved on the inner circumference; the outside has a brushed finish and a small nick at the 2 o'clock position. The ring was a gift from my grandmother and means a lot to me, so I’m really hoping to get it back. If anyone found it, please let me know; I’d be grateful to collect it from the The Hayes area, especially near the library or the Morgan Quarter entrance.
