If you have indicated as place of delivery a country outside the European Union, the prices of the products indicated on the Online Store will be net of VAT.

9. Warranty and technical assistance


Through a careful manufacturing process and rigorous quality control, Monseo seeks to ensure that each of the jewels it produces complies with all the requirements defined by Decree-Law 84/2021 of 18 October. The Company will be liable to the customer in the event of any lack of conformity that becomes apparent within three years of purchase of the jewel.


Within the scope of the legal guarantee, the Customer consumer is entitled to the rights to have the conformity remedied, the price reduced or the contract rescinded as provided for in said Decree-Law, which may be exercised under the terms indicated in the law.


In the event of a manufacturing defect during the first three years after delivery of the jewellery produced by Monseo, the brand guarantees to restore the conformity of your jewellery by means of repair or replacement by an identical model, in cases where repair is not possible.


When none of these solutions is feasible, the Customer may choose to reduce the price or terminate the contract, under the terms defined by law.


The legal guarantee will be performed at no cost to the Customer, including, in the case of repair, labour and replacement of the defective components, if necessary, as well as collection and delivery transport and the respective insurance, the latter also applicable if the jewellery has to be replaced.


Small variations in the tonality and brightness of the pieces, typical of the natural materials used in the manufacture, cannot be considered as defects or imperfections. In addition, although Monseo tries to present the products as accurately as possible, it cannot guarantee that the Customer's device monitor will display a totally accurate colour, so this type of variation cannot be considered a defect either.


The guarantee does not cover defects resulting from normal wear and tear caused by use, misuse, accident, non-compliance with recommended care or any other external cause, including for example loss of stones, scratches, dents, damage caused by modifications, repairs or intervention by third parties not authorized by Monseo.


To exercise this right, you must communicate the lack of conformity of the product to the Online Store via the email This communication must include a description of the problem and be accompanied by a copy of the purchase invoice.


Monseo undertakes to carry out repair, replacement or refund, whether total or partial, as applicable, within a maximum legal period of 30 days after receipt of the product at its registered office.


If the problem cannot be covered by the warranty, Monseo can carry out the repair through its technical assistance services. In this case, a quotation will be presented to you and the repair will be carried out after acceptance and payment of the amount quoted.
