We love aquamarine for a March birthday, and the cool tones of the aquamarine cz crystals on this pair of hoops look great during any season thanks to their cool, uncomplicated style! The 15mm hoops are a super versatile size that easily pairs with your wardrobe. Made from sterling silver they measure 3mm wide and feature a clever hinged opening at the back. The very light blue stones are each 2mm in diameter and sit in a single row of 8 at the front of the hoops.
