The NUBIA mini hoops are small thick rings with a satin finish and irregular texture. These earrings are made from African metal beads, each with a unique shape and texture. Atelier Nicol jewelry is made entirely of brass (nickel-free, hypoallergenic), then coated with a gold bath. The three-micron plating allows each piece to accompany you daily and last over time. The silver-plated jewelry, on the other hand, is coated with a ten-micron silver bath.
