We shape precious metals
to bring out their nature.

About us

For over forty years at the heart of the Vicenza jewellery district.
A story of technical expertise, innovation and quality.

ONE transforms precious metals into precision semi-finished products.

Our product and process know-how covers the full production cycle, from alloy to quality control before shipping. A supply chain controlled at every stage, delivering consistent quality and a concrete commitment to the sustainability of processes and materials.

Four market segments — jewellery, luxury, industry and healthcare — require different solutions. ONE offers every partner flexibility, high quality standards and a range extending from series production to dedicated projects.

From CAD design to finished precious-metal part — luxury

Luxury

Aesthetic excellence and high mechanical performance are fundamental characteristics in the high-end segment.

We develop projects to the customer’s specifications, using platinum and precious alloys.

We oversee every stage from design through to production of the semi-finished part, ensuring high-precision tolerances and finishes.

Metal bars, tubes and strip — semi-finished products for industry

Industry

Resistance to extreme conditions and precision in chemical composition are essential in industrial applications.

We produce wire, microwire, thin-wall tubes and microtubes, strip and bar in engineered alloys for a wide range of applications.

Precious-metal microwire spool — healthcare

Healthcare

Biocompatibility and chemical inertness are essential requirements for many medical and electromedical devices. We produce wire and parts in specific alloys optimised for medical and implantable use.

From scrap material to refined metal — precious metal recovery

Precious metal recovery

You don’t need in-house melting equipment. Process scrap, offcuts, cuttings and spent material can be sent to ONE even in small lots: we weigh it, analyse it and credit the fine-metal content to your metal account, ready to return to production as a new semi-finished product.

A closed loop that puts the value you already hold back into production, reducing procurement costs and environmental impact.
