The ring has nothing to do with the spear point, far from it, it's a poor mans ring and was probably guilded...from the early 1900's.The ring might have been part of the Spear also , on the staff part of the spear , I would check the diameter of the ring and the spear head opening to see if they are the same.? Its worth whatever a collector would pay , Don't Clean it any more though . and if anyone asked , say You found it on Your own property...lol...
