Gold-tone hoops with purple crystal, lost near Bronson Park

I lost my gold-tone hoop earrings yesterday around 3pm near Bronson Park's main entrance on West Lovell Street in Kalamazoo. They’re small hoops about 1.5 cm in diameter, no visible brand tag, and the right hoop has a tiny purple crystal while the left edge has a small scratch. They’re sentimental—my grandmother gave them to me—and I’m really hoping to get them back. If someone found them, I’d be incredibly grateful; they’re irreplaceable to me.
