OUR STORY

The youngest holder of the Brevet des Métiers d'Arts from the Ecole Boulle, specialising in fine jewellery, Yohann also graduated in gemmology from the Institut National de Gemmologie. After working for a number of jewellery manufacturers in Place Vendôme, Yohann took over one of France's oldest jewellery stores at Place Charles De Gaulle in 1998. In addition to his jewellery business, he developed his passion by producing collections for other independent jewellers, becoming a real creative resource for many of his clients.

Marine gained extensive experience in events management and retail before joining forces with Yohann to sell jewellery, watches, and accessories. Caught up in their success, they quickly created Diamanta together in 2001. With distribution spread over 140 independent luxury outlets, DIAMANTA gradually gained a foothold in this segment in France, before democratising a wider range of products under other brands and in new markets.

Together, Marine & Yohann decided to develop a portfolio of brands, each of which would progressively broaden the group's product and price range. Strengthened by a great team, it's by means of creations, model registrations, and innovation patents that the well-known couple develops, year after year, a structured group that meets the different needs of the timepiece and jewellery market. Products that always reflect the essence of their brands: different, innovative.

The separate companies of the two entrepreneurs complement each other, giving rise to the DIADÈME holding company to bring them together. In 2017, DIADÈME regrouped its subsidiaries with an initial capital contribution of 13 million Euros, enabling it to structure a powerful group focused on synergy for new areas of play.
