An 8.5" 925 sterling silver 5mm box chain bracelet with pebble details, brushed and finished with black ruthenium plating. Finished with a pebble detail lobster clasp closure. Made in Italy.

This bracelet is a 5mm box chain produced in 925 sterling silver in Italy, with pebble surface details on the chain links and matching lobster clasp, finished with a brushed black ruthenium surface treatment. A box chain is constructed from a series of square or rectangular hollow links joined in sequence, producing a chain with a smooth, structured surface and a characteristic rigidity and weight relative to a round-link chain of equivalent width. At 5mm, this box chain is a substantial bracelet-width construction — significantly wider than the fine box chains used in necklace applications, and wide enough to register as a bold, architectural element at the wrist. The pebble detail is a surface treatment applied to the face of each box chain link and to the lobster clasp, in which a pattern of small, rounded convex forms — resembling the surface of river-worn pebbles — is worked into the metal face of each link. The pebble texture creates a three-dimensional surface relief on each link whose rounded forms catch and distribute incident light differently from a smooth flat face, and whose consistent repetition across every link of the chain produces a unified surface character from end to end, including on the lobster clasp. The brushed finish is produced by drawing an abrasive tool across the metal surface in a single consistent direction, creating a series of fine parallel micro-scratches that together produce a low-reflectance, directional satin surface. The black ruthenium plating is applied over the brushed sterling silver surface. Ruthenium is a platinum-group metal — one of the six metals of the platinum family — and in its black electroplated form produces a dark, near-matte surface finish that is among the hardest and most durable electroplated finishes available in fine jewelry production. The combination of the brushed preparation and the black ruthenium plating produces a surface that is deep black and low-reflectance: the brushed texture is visible beneath the black ruthenium, giving the surface a directional quality rather than a flat uniform black. Made in Italy.

A significant fine jewelry bracelet for anyone looking for a black ruthenium box chain bracelet in sterling silver — an 8.5" 5mm pebble detail box chain with a matching pebble lobster clasp, brushed and finished with black ruthenium, made in Italy.
