Crafted in Italy from solid 925 sterling silver, this 18-inch necklace presents an enduring interpretation of the classic box chain. The design utilizes a rounded box profile that softens traditional angular links into smooth, cylindrical segments. Machine-made precision ensures consistent alignment across every link, while a polished finish brings out the bright, natural luster of the white precious metal.
Measuring 4 mm in width and weighing approximately 29.79 grams, the solid silver construction provides a noticeable presence and fluid drape suited for versatile unisex wear. An anti-tarnish protective coating shields the sterling silver surface, preserving its radiant shine through continuous wear.
The necklace fastens securely with a fancy lobster clasp, ensuring dependable closure for daily and formal occasions alike. Each structural element reflects dedicated Italian manufacturing, delivering an elevated essential for any fine jewelry collection.
