The details

A sterling silver round box chain necklace in a 4mm width, made in Italy with a solid construction and a polished finish.

The box chain is one of the oldest and most structurally sound chain styles in fine jewelry, formed from square links connected at right angles to create a flexible yet uniform rope. The rounded variation softens the silhouette while preserving the chain's durability and even drape. Italian chain manufacturing is widely regarded as the global benchmark for precision and finish quality.

Jewelry care
  • Sterling silver darkens naturally with air. A silver polishing cloth brings the shine back, and an airtight pouch keeps it there.
  • Put jewelry on last, after lotion and perfume, and take it off before showering, swimming or sleeping.
  • Store each piece on its own in a soft pouch so it doesn't scratch.
