CALDERONI. THE BEST DIAMONDS, GUARANTEED, SINCE 1840.
Calderoni was established in 1840 in Milan’s Via della Lupa, known today as Via Torino. At that time, Milan was a romantic city, dominated by the Habsburg dynasty.
In 1870, Calderoni opened a prestigious establishment in Piazza Duomo, which soon became a point of reference for the city’s aristocracy. Calderoni became the official supplier of the House of Savoy and its prestigious customers included the nobility and royal houses of Europe.
In 1942, Calderoni moved to Via Montenapoleone, symbol and centre of Italian luxury in the European Capital of fashion, design and the jewelry, remains Calderoni’s flagship store in Italy to this day.
