The maker's mark in this ring is in the form of a elongated hexagon, which came into effect in Italy in 1968. The manufacturer of this ring, with the corresponding number '1952' was registered in the province of Alessandria.

Conceived by Giorgio Bulgari in 1932, the very first Trombino Bulgari ring was set entirely with diamonds as an engagement ring for his future wife, Leonilde Gulienetti. The Trombino’s undisputed high glamour profile proved irresistible to the jewellery cognoscenti of the 1930s.

The Trombino is one of Bulgari’s most instantly recognisable and iconic designs. Undeniably eye-catching, the Trombino Bombé cluster was pioneering as it enabled the central impressive gemstone to stand proud as the centrepiece. The broad integrated shank of the Trombino design consists of grain set round diamonds with a graduated horizontally set row of baguette-cut diamonds tapering down from the central gemstone.
