13 Carat Tennis Necklace

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 chain necklaces can make a statement on their own. What’s better than eye-catching chains of yellow gold or subtle silver to accessorize with everything from a designer evening dress to a comfortable sweatshirt?

Personal ornament in general has been around for eons. Ancient Egyptians designed jewelry and wore necklaces, rings and other accessories, and the excavation of King Tut’s burial chamber in 1922 had the greatest impact on Art Deco jewelry. When chain necklaces first took on some visibility in ancient civilizations, these items weren’t exactly democratic.

Chain necklaces were accessories that were relegated strictly to royal families and the upper class. In ancient times, pendant necklaces conferred prestige, for example. Wealthy Greeks and Romans opted for gold and silver necklaces that featured ornate pendants and semiprecious stones. By the Renaissance period, the pendant had replaced the brooch as the most worn type of jewelry. Pendant necklaces were commonplace, or pendants were simply strung on long gold chains.

Thankfully, jewelry became more accessible over time. And trends have come and gone, but the popularity of chain necklaces today owes in part to hip-hop culture. Big, chunky gold chains and diamond necklaces were the order of the day in publicity shoots and on album covers for rappers in the early 1980s onward, and a gold chain is still a mainstay in the ever-evolving and broadening hip-hop culture as we know it.

In our modern era, a number of chain-link necklaces are trending, worn alone or layered. The stylish links that have passed the test of time include oval links, paper-clip chains and more. The best way to discover your perfect fit is to zero in on a particular name and type of link.

While it was once key to accessorizing for a formal event, a vintage chain necklace now adds a fresh dynamic to any outfit at any time of day. Find yours on 1stDibs.
