1965 Bulgari Ruby Emerald Diamond Gold Dolce Vita Ring

Greek silversmith Sotirios Voulgaris arrived in Rome in 1881 and set up his own shop there in 1884, calling it Bulgari, an Italianization of his last name (eventually spelled BVLGARI, using the classical Latin alphabet in a nod to ancient Roman culture). In 1905, he opened the company’s flagship boutique on Rome’s Via dei Condotti.

Although the house found success with its silverwork and Art Deco designs, popular through the 1920s, its signature style — bold, often using yellow gold embellished with big colorful gemstones — began to emerge when Sotirios’s sons inherited the business, in 1932. The brand truly hit its stride in the dolce vita era of the 1950s and ’60s, when the founder’s grandsons Paolo, Gianni and Nicola Bulgari decisively departed from demure traditional styles to develop the house’s exuberant multi-gem looks, attracting celebrity collectors like Elizabeth Taylor.

In the 1940s, Bulgari debuted perhaps its most famous design, the Serpenti bracelet watch. The piece’s snakelike coils were made possible by the tubogas jewelry technique, which links a flexible series of thin horizontal bands. Both the sleek, modern tubogas construction and the sinuous snake motif continue to be synonymous with the Bulgari brand.
