All our jewelry is RJC certified, a label that guarantees responsible manufacturing that respects ethical, social and environmental standards in order to allow true transparency and traceability jewellery.

This jewelry is made entirely of precious metals: recycled 925 silver and gold. All Mayrena jewelry is lead-free and nickel-free. All materials are hypoallergenic.

Polishing, engraving and plating are carried out by a specialist fine jewelry workshop in Besançon.

The layer of 18-carat gold plated on our jewelry is greater than 5µ, a thickness 5 times greater than that of "fine gold" jewelry, guaranteeing greater durability.

A control quality certifying the thickness of the gold is made after each manufacture.

Furthermore, a unique Italian patented finish protects the jewel from the wear and tear of time and the natural oxidation of silver.

For vermeil jewelry, the best way to maintain its appearance is to remove it before cleaning, crafting, playing sports, swimming, showering or sleeping.

Please note that over time, hydroalcoholic gel, water, perfume and rubbing can damage vermeil jewelry. They should therefore be taken care of and cherished.

The base being silver, when you are not wearing it, the best way to protect it is to put it back in its vacuum case after having wiped it with a soft cloth.
