Aquamarine Colored Stone with Crystals Stud Earrings

Aquamarine Colored Stone with Crystals Stud Earrings I think these are costume jewelry, but not sure. It could be a real center stone but since I'm not sure I've priced these accordingly. I don't recall buying these so I can't be sure of the designer or details. Regardless, they are really really pretty! They sparkle so much and really easy to wear and style. Details: -aquamarine colored center stone surrounded by crystals that sparkle different rainbow colors -simple stud back -see photo for size
