Hi, These drop earrings feature Swarovksi crystals with a 6mm center stone of Crystal Clear and a halo of Air Blue Opal. They are the Little sister of the 8mm halo. These are the perfect size for everyday wear and are approx. 3/4" from the top of the ear wire to the bottom of the setting. They were handset by me into high-quality settings of brass with an Antique Silver finish. They are secure and comfortable to wear with a lever back closure. . Thanks for stopping by!
