Lost silver engagement ring with a small round diamond and intricate engravings in Patterson Park.

I lost my silver engagement ring while I was out for a walk in Patterson Park last Tuesday evening. The ring has a small round diamond in the center and some intricate engravings on the band. I've retraced my steps several times, but I can't seem to find it. It holds a lot of sentimental value, so I’m really hoping someone might have found it.
