For sale is this circa 1960's, Juliana D & E Beaded Earrings with Black Diamond Chatons. Black Diamond is the color used in describing these stones, but of course, they are glass. They measure approximately 1 1/2" long and a similar pair can be seen on page 281 of Ann Pitman's Juliana Jewelry Reference Guide. They have some wear to the a/b finish, but only noticeable in my extreme close up pictures.
