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.

Renowned for incorporating awe inspiring gemstones into their creations, Bulgari introduced dramatic combinations and their use of cabochons became a hallmark of the brand to glorify the vivid colour of gems. One of the most famous Trombino rings was bought by Elizabeth Taylor in 1971 and consisted of a magnificent sapphire cabochon.

This ring is in excellent condition.
