The Florentine Diamond's lengthy and complex history has entered a new chapter. The Tuscany Region has begun direct conversations with Charles of Habsburg-Lorraine, the head of the House of Habsburg and current owner of the famous diamond, with the goal of temporarily returning it to Tuscany. This is the first official contact initiated by an Italian institution and solely committed to the diamond's future. The initiative is based on historical and factual research conducted by the Region in partnership with the Museo de’ Medici and the Florence State Archives. The analysis and digitization of documents relating to the succession between the Medici and Lorraine dynasties revealed a significant passage: in the annex to the Family Pact of 1740, Anna Maria Luisa de' Medici established that the Florentine Diamond should remain "united with the State of Tuscany". According to Eugenio Giani, President of the Tuscany Region, this is a historically significant and clearly documented element. The diamond, he clarified, was meant to remain the public property of the Grand Duchy, for the benefit of visitors and as an adornment of the State, symbolizing one of the most significant legacies of the Electress Palatine. Based on this premise, the dialogue with the heir of the House of Habsburg seeks, in an initial stage, to coordinate an exhibition that will facilitate the jewel's return to Florence, with the aspiration of securing a permanent concession in the future. Regional Councilor for Culture Cristina Manetti also underscored the symbolic and identity-enhancing significance of the initiative, noting how a historical issue long in the shadows is now resurfacing thanks to research conducted, paving the way for a possible return of the diamond to its land of origin. Strengthening the path of enhancement is a recent iconographic discovery: an unpublished portrait of Grand Duchess Maria Maddalena of Austria, attributed to Orazio Fidani. The work, illustrated by Samuele Lastrucci, director of the Medici Museum, depicts the sovereign with the Florentine Diamond and constitutes, to date, the most comprehensive pictorial record of the jewel known. Acquired in its raw form in 1601 by Ferdinando I de' Medici and subsequently cut in Florence during the reign of Cosimo II, the Florentine Diamond disappeared from public sight after World War II, when it was entrusted to Empress Zita of Bourbon-Parma. The negotiation initiated by the Tuscany Region now reopens the debate on its future and its historical connection to the Tuscan territory.
