Why steel rather than silver? Because TESEO jewelry is made to be worn every day, not kept in a box. 316L steel does not tarnish or rust, whereas silver oxidises and needs regular care. Much harder than silver, it stands up better to knocks and scratches and keeps its shape. Wiped with a soft cloth, your piece keeps its colour for years. More about our materials

Will the gold fade?
The plating on 316L steel is made for daily wear. With simple care, it keeps its colour for years.

Can I wear it in the shower or the sea?
Better to take it off: water, chlorine and salt can dull the gold plating and natural stones over time.
