Love these beautiful earrings. I am a collector of the KS gumdrop stud earrings and have them in multiple colors. To me, this is almost like the pearl version of that earring, just slightly smaller. As far as I can tell, these are authentic, and have compared them to my KS gumdrops  purchased from a KS boutique. I like to wear both the gumdrops, and these  alone  or with earring jackets  for versatility, and a fashion forward look. Love them! Thank you Amazon.
