All CERVERA jewellery complies with the certification and guarantee standards for precious metals of the highest quality. This is reflected in the physical form of the pieces by means of the contrasts established in the Spanish regulations for objects made with precious metals.

Each piece of jewellery manufactured in our workshops in Barcelona carries:

A contrast of identification and origin: the Cervera teardrop is engraved on each piece as a sign that it has been made in our workshops and identifies us as manufacturers.

A guarantee contrast: a mark made by means of a punch by an official or authorised laboratory, duly authorised to carry out this task. The laboratory marks each piece with a punch, in a different way for gold and silver, which guarantees compliance with the highest standards of quality and guarantee.
