French made jewelry guaranteed by the Res Mirum hallmark.


Our jewels are in silver 925‰, which corresponds to the highest legal title in France and in most countries. We also say silver 1st title. 925‰, this means that it is an alloy composed of 92.5% of pure silver and 7.5% of various metals (notably copper); this association of various metals is necessary in order to give the alloy better mechanical properties, notably greater hardness. This alloy, in accordance with legislation, does not contain nickel. We mention that it is solid 925 silver; the word solid here means that the jewels are full, and that the titration of the alloy is homogeneous throughout its volume.

The fact that our jewelry is made of 925 silver is attested in 2 ways:

- by the mention "money 925‰" on our invoices,
- by affixing our manufacturer's hallmark (also known as the responsibility hallmark) on each piece of jewellery. This hallmark is diamond-shaped and consists of the initials of our company around a passion flower. This hallmark, which belongs only to us, has been deposited at the customs office and is our responsibility. The works that weigh more than 30g are also stamped with a state hallmark representing a head of minerva.



Your purchases are of course also covered by the legal guarantees of conformity and hidden defects, which run for up to 2 years. Do not hesitate to see our GTC for details of these guarantees. If you encounter a problem with your jewelry, first of all do not hesitate to contact us. We will do our utmost to satisfy you. And if, despite all our efforts, you are not satisfied, we join a mediation organization so that you can benefit from the services of a mediator free of charge.



If you have the slightest problem, we will do our best to offer you the best solution as soon as possible. Do not hesitate to contact us via one of the means proposed on the page Find us.

Our jewellery is designed to last, but if it breaks, we will be able to repair it. If the repair does not fall within the scope of the above guarantees, we will tell you the price of the work; and unless your jewelry is really in very bad condition, it will always be more interesting to repair it rather than to buy another one.

If you are able to present the purchase invoice of your jewelry, we will apply a special rate.



With each purchase, we send you an invoice by email.
This invoice serves as a certificate of authenticity; it includes a description of your jewel, the precious metal it is made of, its titration and weight, as well as your identity.

We invite you to keep this invoice; it can be useful to you to prove your purchase, to be reimbursed by your insurance in case of theft for example, but also in case you have to contact us in case of a problem, for a repair, in particular.
