Guarantee

of Authenticity

All Madjoi jewels are conceived as artistic works and many are registered as such in the Intellectual Property Registry.


At the time of sale, all jewelry is dispensed to customers with a printed Certificate of Authenticity and a digital Certificate of Authenticity, based on blockchain technology.


The blockchain digital certificate of authenticity is essential to guarantee the value of the work to the buyer, but it also scrupulously includes all the elements that constitute the work: the description, the computer media, the legal mentions of authenticity and the rights of use
