SUSTAINABILITY

RESPONSIBILITY AND CONSISTENCY

TeNo Design partner and wedding rings, as well as jewelry, are created in close partnerships exclusively in European workshops. For us, sustainability means not producing short-lived trends, but rather focusing on materials and manufacturing processes designed for durability and ethical responsibility.

Our jewelry and accessories are crafted in specialized workshops, which we carefully select for their artisanal expertise and fair working conditions. These long-term partnerships allow us direct control over compliance with social and environmental standards at the production sites.

At TeNo, technical materials meet precious accents. Whether as an inlay in tantalum rings or as a setting for diamonds: all precious metals we use, such as gold, silver, platinum and palladium, come 100% from recycled sources and not from new mining.

Our partners for processing these metals are members of the Responsible Jewellery Council (RJC) . Through certification according to the strict RJC Code of Conduct, we guarantee respect for human rights, fair working conditions, and environmental responsibility throughout the entire supply chain.

  • Origin: We guarantee that our natural diamonds come from legitimate sources that comply with UN resolutions (Kimberley Process).
  • Lab Grown: As a modern and resource-efficient alternative, we offer diamonds from certified laboratory cultivation. These are physically and optically identical to mined diamonds, but offer a completely transparent origin history.

Extracting metals like titanium, tantalum, and stainless steel requires energy. Our answer to this is uncompromising durability instead of a throwaway culture.

  • Lifespan: TeNo jewelry is virtually indestructible, skin-friendly, and corrosion-resistant. Each piece is designed to last for decades.
  • Cycle: Titanium and steel have an extremely high recycling rate and can be reintroduced into the material cycle again and again without loss of quality.

We source the leather for our watch straps from a long-standing European partner who operates according to internationally recognized management standards. Our main leather supplier is certified according to ISO 14001 (environmental management) and ISO 9001 (quality) . This ensures systematic environmental management and the continuous improvement of sustainable production processes directly on site.
