Louis Vuitton has obtained Responsible Jewellery Council certification, confirming its daily implementation of the ethical, social, societal and environmental principles promoted by the RJC. All precious metals and diamonds used in our jewellery and watch collections come from partners who are also RJC-certified.

Louis Vuitton diamonds have been purchased from legitimate sources not involved in funding conflict, in compliance with United Nations resolutions and corresponding national laws. Louis Vuitton guarantees that these diamonds are conflict-free and confirms adherence to the WDC SoW Guidelines.

Louis Vuitton diamonds are exclusively of natural origin and untreated, based on personal knowledge and/or written guarantees provided by the supplier of these diamonds.

For its pavé-set diamonds, Louis Vuitton selects diamonds with a colour grade between D and G and a clarity grade between IF and VVS.

The use of colourless fluids and heat treatment is recognised as a traditional lapidary practice in addition to the cutting and polishing of certain coloured gemstones, as well as the bleaching of pearls. Our gemstones may have undergone these general enhancement practices.
Pavé-set sapphires and rubies may have been heated.
Pavé-set emeralds may show traces of colourless oil.

Louis Vuitton guarantees that the diamonds and diamond-containing products have not been cut from diamonds originating in, exported from or transiting through Russia after 31 December 2023.
Louis Vuitton further guarantees that the diamonds and diamond-containing products with a weight equal to or greater than 0.5 carat or 0.1 gram per diamond have not been cut from diamonds originating in Russia or exported from Russia, even if they were processed in a third country.
Louis Vuitton is able, upon request, to provide supporting documentation substantiating this declaration, which Louis Vuitton undertakes to continue to comply with.
