This is the Arctic Grayling Cuff Link. The photo is of the highlighted version. It is also available in the Original version which means it comes with just a black enamel painted eye.
Once native to northern Michigan(near me), but has now gone extinct due to lumbering in the last century, they are still found in a few places within the United States. There are small populations of it out west and you can find it in pretty good abundance in Alaska. It’s still on my checklist to catch.
The unusual shaped, colorful dorsal fin is what is the unique feature of this species.
It is available in 14K Yellow or White Gold. Please allow a minimum of 2 weeks for all gold orders.
