The details
Clean lines and a high-polished surface make this solid sterling silver box chain one of those pieces that works with everything. Each square link is cast with crisp right angles and a mirror finish that catches light from four sides, giving the chain a presence that reads well whether it sits close to the collar or drapes lower with a pendant.
Made in Italy, the chain carries the precision that Italian fine chain production has long been associated with. The lobster clasp closes firmly and holds through daily wear, and because the metal is solid sterling silver all the way through, the chain polishes back to its original brightness whenever it needs refreshing.
