Abstract ceramic wall plaque, 8x10 inches, gold accents

Hey there, I lost my handmade abstract ceramic wall plaque yesterday around 3pm outside the El Paso Museum of Art on Arts Festival Plaza. It's a small 8x10 inch piece with a matte white base, cobalt blue glaze swirls, and subtle gold leaf along the edges. The frame is light oak and has a couple of tiny scratches on the corner from being bumped around. There's a signature in the bottom-right that reads 'M. Rivera.' It means a lot to me—it's a gift from a friend who helped me through a rough patch, and I’d be really grateful to get it back. If you found it, text me near the museum.
