This is the Jumping Arctic Grayling Lapel or Tie Tack.
Once native to northern Michigan(near me), but has now gone extinct due to lumbering in the last century, it is 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.
The unusual shaped, colorful dorsal fin is what is the unique feature of this species.
This is the same casting I use for the “Jumping Fish” pendants and also as stud earrings. It would make a nice set.
Gold orders need min 2 weeks.
