Jewelry manufacturer in Poland

Argentum is a Polish jewelry manufacturer with roots since 1920. We make jewelry in 925 silver, gold and titanium — custom and under the client’s brand — in our manufacture in Koszelówka near Płock. Made in EU.

Jewelry manufacturer in silver, gold and titanium

Argentum is a Polish jewelry manufacturer operating continuously since 1920 — today run by the fifth generation of the same family. We make a full range: earrings, pendants, rings, wedding bands, bracelets, chains and signet rings — in 925 silver, gold and titanium. We deliver brands’ own collections and contract manufacturing on commissioned designs — from a single prototype to 15,000–25,000 pieces a month, entirely in-house in Poland.

Materials: 925 silver, 585/750 gold and titanium

We work in 925 sterling silver, 585 and 750 gold and titanium. We offer full electroplating: rhodium, gold and silver plating, plus oxidising. Titanium is our differentiator — anodizing gives durable colours without coatings, and laser welding joins parts beyond classic goldsmithing. We advise on material and finish to suit the product’s function, brand positioning and budget.

The full production process under one roof

Design and 3D model (CAD), prototype, casting, CNC machining, laser engraving and welding, electroplating and hand finishing — every stage done in-house. Full in-house production means repeatable quality, control of deadlines and fast repeat runs. We can recreate an existing model, develop your sketch or design a collection from scratch.

Custom production and private label

We deliver custom production and private label and white label (OEM/ODM) under the client’s brand, with full project confidentiality. We work with brands, wholesalers, shops and institutions across Europe. The mould and design know-how remain the client’s property.

Minimum order, lead times and pricing

The minimum order is 10 pieces per design; you can combine designs in one order. Lead time is usually about 6 weeks from order confirmation, with the prototype prepared earlier. The unit price is given after prototype approval — split into metal and labour. We explain how volume affects price in MOQ in production.

A century of craft — Made in EU

Five family generations and a century of continuous production. Over 60% of our production staff have 20+ years of experience, and our ~450 B2B partners include brands and wholesalers across Europe. Production in Poland means Made in EU — a shorter supply chain, European standards (REACH, hallmarking) and full quality control. See our story or send an enquiry.
