The cubic zirconia crystal on this necklace is coloured a beautiful emerald colour making it an ideal gift for a May birthday. The stone measures 3.5mm wide and is round cut. It sits snugly in a claw setting to allow the most light to shine through the stone. This setting hangs from a jump ring threaded along the sterling silver diamond cut curb chain, designed to sit close to the skin and sparkle brighter than a standard curb chain. The chain is secured with a spring ring clasp and can be ordered in lengths from 14 to 32 inches.
