The exact year of the jewelry's foundation in Via Dora Grossa (now Via Garibaldi) in Turin is unknown. What we do know is that in 1850 the firm "Fratelli Borani" - purveyor to the "Real Casa di Sardegna" and to the "Regi Ministeri" (Royal House of Sardegna and Royal Offices) - dealt in gold, silver and honorary badges. In 1864 the same firm opened a shop in Florence - where the capital had been temporarily established - and finally, with the country's unification, it moved it to Rome.
When the Borani brothers retired from business, the firm passed on to Domenico Cravanzola and, in 1913, to Luigi Raviolo and Enrico Gardino. In 1927 Ettore Gardino, Enrico's son, bought Luigi Raviolo out, and changed the jewelry's name into "Gardino Succ.ri Ditta D. Cravanzola s.a.s." as it still is today.
In 1980 the firm became an authorized dealer for Rolex watches, anticipating the development of what will soon turn into the world's leading brand in the field.
The structure has been restored in 1993, with permission from the Department for Historic Preservation of the City of Rome, as both the building and the furniture (dating 1850) are considered national heritage, and therefore under protection.
