Hi, These earrings feature Light Sapphire Swarovski crystals in the 8mm size. PLEASE NOTE these are picturing darker than they are in person. I have posted a stock photo showing the truer shade of blue for reference. They really pop in the wavy rope design setting, like the most beautiful Caribbean waters. These 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. The setting is approx. 15.5mm (1/2 inch) with a total drop of 1" and 1/8 from the top of ear wire to the bottom of setting.
