The ONDA studs are two asymmetrical earrings that evoke the wavy shapes of the waves. One simple side simply encircles the lobe and one double side additionally hooks inside the ear for an earcuff effect. Since each lobe is different, feel free to slightly fold the earcuff side hook to fit the shape of your ear. Atelier Nicol jewelry is entirely made of brass (nickel-free, hypoallergenic), then coated with a layer of gold. The three-micron plating allows each piece to accompany you daily and last over time. The silver-plated jewelry is, on the other hand, covered with a ten-micron layer of silver.
