This is the Walleye Stud Earring. It is the same casting used in the “Jumping Fish” Series of Pendants and makes a great set! The earring will come with an enameled black eye. At this time I don’t have an updated photo, but you can reference the jumping fish pendant picture.
I grew up in the Midwest where the Walleye Run in the Spring is a big deal with the anglers. I recall the days of wading elbow to elbow trying my luck to catch these fish with a jig. I now catch them up in Northern Canada on a fly.
