Lost gold engagement ring with a small diamond near the lakeside park nature trail in Northern Wisconsin.

I lost my gold engagement ring while walking on the nature trail near the lakeside park in Northern WI last Sunday. It's a simple design with a small diamond, and it holds a lot of sentimental value to me. I've retraced my steps but haven't been able to find it. If anyone has seen it, I would be so grateful if you could reach out.
