Lost silver swallow-shaped pendant with intricate detailing and a small blue gemstone near Del Rio Park.

I lost a beautifully crafted silver pendant shaped like a swallow while I was enjoying a walk near the Del Rio park last Sunday afternoon. It has intricate detailing and a small blue gemstone in the center. I didn’t realize it was missing until I got home, and I’ve retraced my steps but haven’t had any luck finding it. It holds sentimental value, so I’d appreciate any help in locating it.
