Bvlgari Diamond Ruby Gold Serpenti Bracelet

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 (in the brand's logo, it's styled 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. Since then, Bulgari has looked to Rome as a source of reference for its fanciful and decidedly romantic designs for necklaces, bracelets, earrings and other accessories.

Although the iconic jewelry house found success with its silverwork and Art Deco designs, popular through the 1920s, Bulgari’s 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. 

On 1stDibs, the collection of vintage Bulgari jewelry includes rings, pendant necklaces, watches and other accessories.

Antique diamond rings, diamond tiaras and dazzling vintage diamond earrings are on the wish lists of every lover of fine jewelry. And diamonds and diamond jewelry are primarily associated with storybook engagements and red-carpet grand entrances — indeed, this ultra-cherished gemstone has a dramatic history on its hands.

From “A Diamond Is Forever” to “Diamonds Are a Girl’s Best Friend,” pop culture has ingrained in our minds that diamonds are the most desired, the most lasting and the most valuable gemstone. But what makes the diamond so special? Each stone — whether it’s rubies, sapphires or another stone — is unique and important in its own right. April babies might claim diamonds for themselves, but just about everyone wants this kind of sparkle in their lives!

There are several factors that set diamonds apart from other stones, and these points are important to our gem education.

Diamonds are minerals. They are made up of almost entirely of carbon (carbon comprises 99.95 percent; the remainder consists of various trace elements). Diamonds are the hardest gemstones, ranking number 10 on the Mohs Hardness Scale. Even its name, diamond, is rooted in the Greek adamas, or unconquerable. The only object that can scratch a diamond is another diamond. Diamonds are formed deep within the earth at very high temperatures (1,652–2,372 degrees Fahrenheit at depths between 90 and 120 miles beneath the earth’s surface) and are carried up by volcanic activity. Diamonds are quite rare, according to the Gemological Institute of America, and only 30 percent of all the diamonds mined in the world are gem quality.

In the 1950s, the Gemological Institute of America developed the 4Cs grading system to classify diamonds: clarity, color, cut and carat weight. Not all diamonds are created equal (there are diamonds, and then there are diamonds). The value of the diamond depends on the clarity (flawless diamonds are very rare but a diamond's value decreases if there are many blemishes or inclusions), color (the less color the higher the grade), cut (how the diamond’s facets catch the light, certain cuts of diamonds show off the stone better than others) and carat weight (the bigger, the better).

When you start shopping for a diamond engagement ring, always prioritize the cut, which plays the largest role in the diamond's beauty (taking the time to clean your diamond ring at least every six months or so plays a role in maintaining said beauty). And on 1stDibs, a range of buying guides can be found for those in the market for antique engagement rings, vintage engagement rings or Art Deco engagement rings.
