This lovely set of earrings and 2 dress clips is by Hattie Carnegie. The faux rubies are 3/4" on the dress clips and and earrings. The rhinestones fronds are 1" and smaller. The dress clips are 1 3/4" wide and 1 1/4" tall. You may not have a square neckline, so you can use one clip. You could also thread a thin chain under the clip. Marked Carnegie on the earring clips. The white rhinestones are clear. Lovely Christmas set. Great gift.
