Boucheron Serpenti Ring

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.

Vintage choker necklaces are elegant, alluring and stylish. Cameos, pearls, diamonds and other stones can decorate these necklaces, which come in single or multiple strands. Whether it is a statement piece or a delicate chain, these short necklaces always stand out and turn heads.

The history of the choker can be traced back thousands of years, with Sumerian examples discovered from 2600–2500 B.C. They endured as a popular form of adornment through the centuries, and during the French Revolution they took on a symbolic significance. Women wore ribbons around their throats to mark the passing of those killed by the guillotine. Soon, the plain ribbons were adorned with small cameos and other ornamentation.

European choker necklaces gained a salacious reputation in the 19th century when prostitutes were associated with black ribbons tied around the neck, such as the model in Édouard Manet’s Olympia (1863). Queen Alexandra, Princess of Wales, reversed the trend in the late 19th century by wearing a large pearl and diamond choker, reputedly to hide a scar.

Fashioned from gold, pearls and other precious stones and metals, chokers continued to be worn into the 20th century, alternately statements of wealth and rebellion. They experienced periods of revival in the 1920s, ’40s, ’70s and ’90s for both men and women.

Vintage chokers make a statement with an unmistakable air of femininity. On 1stDibs, find an alluring collection of vintage chokers today, including gold, sapphire and emerald chokers.
