The SUMERIA ring is a wide adjustable band where the reticulated texture, different each time according to the piece, recalls the finest antique jewelry. At its center, two fine stones of different sizes. Size to be indicated in order. Atelier Nicol jewelry is entirely made of brass (nickel-free, non-allergenic), then coated with a gold bath. The three-micron plating allows each piece to accompany you daily and to last over time. The silver-plated jewelry, on the other hand, is coated with a ten-micron silver bath.
