Clyde Dunier 14K Gold Sapphire Knot Earrings

Designer 14K gold stud earrings are signed 14K CID and feature approximately 4mm Sapphires in 3/8 inch Knot settings.  They weigh 3.5 grams, so they are heavy for their size, and they are in great vintage condition.  I will point out that one earring back is original and the other is 14K gold but not original.
