After completing a degree in Art with a concentration in Architecture, Eleonora Mantini began her career as a designer in Rome working alongside renowned goldsmith, Professor Mario Turrini, whose laboratory’s focus is on the construction of jewelry, beauty design research and methodology, and gold sculpture.


In 1996, Mantini earned a diploma at the European Institute of Design in Rome. During the final year of her studies, she collaborated with the Cimento Society, working on and creating a collection of pieces inspired by architect Andrea Palladio. Simultaneously, Mantini was creating a line of accessories for the Lancetti Fall/Winter collection.


By 2000, Mantini was awarded second place in the “New Talent” competition held by esteemed architect Massimo Zucchi (during the “Vicenza Oro” fair), as well as being named among the finalists in the Diamond Design Awards competition, “Diamonti Domani,” organized by the world’s leading diamond company, De Beers.


Later, Mantini decided to leave Turrini’s workshop and immediately began collaborating and designing with the Gianni Caritá Company, one of the most important Italian producers of jewels. At that time, Mantini joined forces with Parsifal, for which she designed and monitored the modeling and forming of prototypes.


Before founding her own jewelry line, Mantini held a number of important roles in various collaborations with designers, fashion houses and workshops throughout Europe: she has worked with important names such as Arata Gioielli of Valenza, L’Esagono of Rome and Camillo Bona in the production of high fashion jewelry for her Spring/Summer collection. Additionally, Mantini designed the pearl jewelry collection for Majorca S.A. of Barcelona, she collaborated with Emmetre Gioielleria by Mario Meola (Tari), and Antonimi in Milan on their jewelry design line, “jewels in motion.”...


In 2000 Mantini established Clee Gioielli, a company focused on the creation and production of fine jewelry in gold and precious stones. Her collections are characterized and identified by their style, design, construction, Italian creativity and skill, and the expertise gained through many years of working with the masters of gold and jewelry design. Mantini’s techniques and concepts are forever evolving, as she is on a continuous search for new forms of beauty and precious materials.

Her company’s collections have gained a position in the storefront displays of the finest jewelry retailers in Italy and Mantini’s designs are often worn by noted individuals throughout Europe.
Mantini’s profound love for diamonds and frequent travel throughout Hong Kong, India, New York and Belgium serve as continuous stimuli for the creation of new and innovative collections.
