During an interview for my book Diamonds, Nicola Bulgari used an unforgettable phrase to explain the Italian firm’s playful use of rectangular gems: “We flirt with the baguette.” The romance has clearly gotten serious. Decorated with 28 tapered ruby baguettes, this bold gold ring was turned a dark, sexy night color with a PVD treatment. I know I am in love.
