Rinaldo, Floriana and Stefania Cusi are the owners of the jewelry store of the same name in Corso Monforte 23, in Milan. They had an original idea dedicated to Expo 2015: until Saturday, November 22, the store will host an exhibition of drawings dedicated to the other Universal Exhibition that took place in Milan, the one in 1906. There is a reason: the drawings on display in the store are those of their great-grandfather, Annibale Cusi (1863-1930), who received the Grand Prize for decorative arts for that historic event. In short, a link with the history of goldsmithing: in fact, Annibale Cusi won the award thanks to the creation of a spectacular Maria Stuarda-style collar necklace, completely articulated, in platiuralium: a very light alloy designed by Cusi himself. The jewel was adorned with 15 thousand diamonds that, according to those who saw it, evoked the appearance of lace. Flanked by his son Rinaldo (1895-1979), the Milanese jeweler became a supplier to His Majesty the King of Italy and to HRH the Count of Turin and the Duke of Aosta. As can be read in the jewelry chronicle, in 1922 the Cusi family built Palazzo Cusi in Milan, at via Clerici 1, the new headquarters of the jewelry store, factory and family home. Here, after Annibale’s death, his son Rinaldo continued the business, then his grandchildren Ettore and Roberto and, finally, his great-grandson Rinaldo Cusi, who in 1996 opened the current jewelry store in Corso Monforte, where he continues the business together with his wife Floriana and daughter Stefania, who represents the fifth generation.
