Fabio is the hands. Training at the Istituto d'Arte, specialisation in the Florentine workshops, the art learnt by working alongside skilled artisans. He is the creative soul of the workshop: at his bench ideas become jewellery, and the ideas — he says — arrive when they feel like it, sometimes at night.

Francesco is the stones. Years of experience in the world of diamonds, gained in Firenze: the selection of the gems is his, and so is the commercial side, and the investment diamonds with international certification — GIA, HRD, IGI. He is the reason why the workshop buys and mounts the stones through a short chain, with no middlemen: the person who chooses the diamond is from the same family that sets it for you.

Two skills that in large jewellers' sit in different departments. Here they sit two benches apart, and talk to each other all day long.

The workshop's most important work is the one that is in no window at all: the bespoke piece. The customer arrives with a precise idea, or with a vague one, or gives a free hand. It starts with the drawing, the stone is chosen, the piece is built — piercing, repoussé, chasing, burin engraving — until the object matches the person who will wear it.

It is the heart of the work on wedding bands and engagement rings: rings meant to last as long as the promise they stand for, made by hand for two particular people. And it works the other way round too: in the Tosi workshop the jewellery of the past is repaired, restored, transformed. Family gold that nobody wears any more comes back to the bench and leaves it in a new shape — same material, same memory, another jewel.

From June to September the workshop doubles: at Saltino, inside the Vallombrosa nature reserve, the seasonal boutique opens — via Carducci 3/5, opposite the Grand Hotel Vallombrosa. Holidaymakers come down from the fir woods and find in the window the pieces born in winter at the Tosi bench.

Two addresses a few kilometres apart, a single workshop: the studio stays in Tosi all year round, and it is there that every piece begins.

Alongside certified natural diamonds, for some years now the workshop has also offered Lab Grown diamonds: stones grown in a laboratory, certified, sustainable. Not a renunciation of tradition — an extension of it: the same Florentine style, the same bench, one more material to choose from. And for anyone wanting to sell or part-exchange their own gold, Fabio and Francesco are entered on the OAM, the register of professional gold dealers: transparency is part of the service.
