Jewelry manufacture

Argentum is a family jewelry manufacture operating continuously since 1920. We combine hand goldsmithing with modern in-house production in Koszelówka near Płock.

What a jewelry manufacture is

A manufacture makes jewelry with a large share of hand work and attention to detail — combined with a machine base for repeatability. Both worlds meet under one roof here.

The full process in-house

Design and CAD, casting, CNC and laser machining, hand finishing and electroplating. See custom production.

A century of experience

Five family generations and over 60% of staff with 20+ years of tenure — a rare combination of tradition and scale.
