The Bulgari Trombino ring is a style made famous in the 1930s by the Roman fashion house. The name refers to the Italian word for trumpet (trumpet): the piece features a large central gemstone set on a broad diamond-paved base that widens at the top. It’s an even more sought-after ring if the gemstone is of great value. Such is the one up for sale at the Bolaffi jewelry auction, scheduled for Tuesday, October 7th at the Turin headquarters and Wednesday, October 8th via live online auction. Up for sale is a vintage Bulgari Trombino ring in platinum from the early 1970s, featuring a particularly high-quality pink diamond.
The pink diamond is a rectangular step-cut diamond and weighs 3.18 carats. The stone is accompanied by a GIA certificate describing it as Natural Fancy Intense Pink, VS2, Type IIa. Alongside the largest stone are 64 round brilliant-cut and baguette-cut diamonds, totaling 1.93 carats. According to Bolaffi, this particular Trombino ring stands out because the pink diamond is of exceptional size for this type of gem. The estimate is €800,000-€1.2 million. The ring also has a story: it was passed down from grandmother to young granddaughter and worn for years without fully understanding its value, as the diamond was mistakenly believed to be simply rose quartz. The appraisal by the auction house’s experts revealed its true nature as one of the rarest diamonds in the world. A pleasant surprise.
A natural pink diamond is already a highly sought-after piece in itself, but one weighing more than three carats becomes an absolute rarity. If it is then set in a Bulgari creation, it becomes a one-of-a-kind piece. Whoever is lucky enough to win the lot will win not only an incredible diamond, but a unique and unrepeatable jewel.
