I wonder how this ring got in a park in arizona

Today was a silver day:
2 silver rings (one with a heart, one with buffalo turquoise)
A silver ladybug stud earring
The handle of a silver spoon
The pin from someone’s 200 bowling game was interesting. We also found our first titanium ring, a VFW ring, a bling ring, 2 wheaties, a Mexican 20 centavos, several bits and pieces of jewelry and over $14 in change.
We rich!
