These stunning 9ct gold stud earrings capture the wonder and mystery of the northern lights in their breath-taking, multicoloured crystals! The 4mm, cubic zirconia stones are round cut and held in 6 tiny claws. This allows light to enter the crystal from both the front and sides resulting in more depth to the sparkle. This pair of earrings are supplied with a pair of unobtrusive yet secure butterfly backs and measure 12mm from the front to the back of the pins.
