The workshop

The workshop

Aliseda started in 1990 creating jewels of traditional Florentine school, but very soon our style was enriched by archaeological motifs, especially from Etruscan and Roman sources.
Shapes and working techniques are taken from ancient sources, however creativity and experimentation are very important in producing our jewellery.
Our manufacturing process starts from pure metals to obtain the various alloys used; some alloys such as electrum (gold and silver in equal parts) have been ”rediscovered” after their disappearance from modern jewellery.
Our gems are cut from carefully chosen natural crystals, sometimes using ancient cutting patterns like those published in Diderot and D’Alembert’s Encyclopédie. Tuscan jasper and chalcedonyare often used in our work, as are other hardstones and natural materials.


Chiara daughter of Manuela and Alessandro, attended the Aliseda laboratory as a child, naturally absorbing her parents’ skills. After scientific high school, she expanded her artistic skills by studying tailoring and sculpture in Bologna and drawing in Arezzo. In Ireland she attended courses of specialization in silversmithing with Brian Clarke, in Arezzo and Florence, with expert goldsmith masters, she studied in depth the techniques of the openwork, engraving, settings gems, wax modeling and jewelry making. Over the years she has become passionate about the Etruscan technique, learned in the family laboratory. Using this technique wisely, she makes ornaments that are never simple copies, but the result of a creative project. The essentiality of the forms is at the base of her jewels, a simplicity that implies a meticulous work of intertwining, welding, joints and combinations. Chiara elaborates and completes the professional experiences of Manuela and Alessandro, in this sense her jewels summarize the historical and artistic study, the experimentation, the elaboration of the forms obtained almost always from those of the Tuscan nature.



Manuela studied jewelry with renowned Florentine goldsmith masters, including ancient lost wax master Hubert Schuster. Sculptor and model designer, inspiration behind the founding of the Aliseda workshop in Montepulciano in 1990, Manuela Petti creates soft and sinuous forms that express an elegant equilibrium between ancient and modern that remain grounded in the integrity of the goldsmith’s canon. Recently, Manuela manifested her passion for sculpture in a series of bronzes inspired by the Etruscans. The originality lies in the patina, a beautiful bluish green achieved by applying ancient recipes to natural substances and which took three months in a tuff cave to obtain. Finely finished with a chisel as in the Renaissance, Manuela gave the bronzes their final touch of perfection and elegance.


Alessandro Pacini’s work isinspired and informed by the richness of archaeological material. A Goldsmith specializing in archaeometallurgy, Alessandro applies techniques completely consistent with ancient ones to his creations. Alessandro also applies procedures found in ancient documentary sources such as the medieval manual of the monk Teofilo. Alessandro has reintroduced forgotten techniques and materials such as lead-free niello, electrum, and cloisonné with garnet slices. Alessandro studied the History of Jewelry in the University of Florence. From 1992 to 2006 he and EdilbertoFormigli directed seminars on archaeometallurgy at the important archaeological site in Murlo (Siena). Since 2000 and to date, Alessandro has been a lecturer at the School of High Education of the Opificio delle Pietre Dure in Florence.


Andrea Pacini trained at the I.RI.GEM. School, Gemological Research Institute of Veneto. He learned the ancient technique of the Florentine Commesso, a type of mosaic with hard stones, at the renowned Lastrucci workshop in Florence and he had the opportunity to study ancient gems from close up of which he repeated the cuts. Choose only natural material without any treatment, recently proposed Tuscan gems such as alabaster or chalcedony enhancing the natural colors with the cut.


Founded in 1981, Spivach & Spivach Opals are brothers Sergio and Stefano, top quality opal cutters. Based in Udine-Italy, this family-run artisan opal cutting studio has been handed down by their devoted, loving and talented father Luciano. It is with experience, passion and skill that the opal is taken from the mine through to the cutting process, whereby Sergio & Stefano transfer not only their expertise but also their themselves.


Nicola Bacocchia, restorer carpenter, make cases for Aliseda designed and make entirely by hand with essences typical of our areas, such as the poplar and the chestnut, the elm, walnut or cherry. Nicola uses ancient techniques, such as hand planing, shellac or oil finishing.
