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.

Earrings are a timeless accessory. Women have been wearing studs and hoops in civilizations as far back as Ancient Egypt. Diamond drop earrings, pearl versions and other antique drop earrings have a long history as well.

While hoops will always be beautiful, drop earrings hold their own as dazzling accessories, and jewelry designers have explored different variations on this style of earring over time.

Although the term is often misapplied, true drop earrings are characterized by a long lean line ending in a pear-shaped stone that drops just below the earlobe. These accessories were popular in the Art Deco era, which encompassed the 1920s and ’30s and ushered in a very distinct look in jewelry design.

There were many influences on Art Deco jewelry; among them, the excavation of the tomb of King Tut in 1922. “Egyptomania” left an indelible mark on all of the major jewelry houses, from Cartier to Van Cleef & Arpels, Boucheron and Georges Fouquet. Today, the popularity of long Art Deco drop earrings can be attributed to the influence of Coco Chanel. These earrings are frequently characterized by simple shapes, clean lines and an integration of colorful stones such as blue sapphires, emeralds and rubies to accent the pieces’ diamonds. Indeed, during the 20th century, as technology for diamond cutting improved, diamond drop earrings and other diamond jewelry came into wide popularity. Formal examples of diamond drop earrings pair perfectly with a cocktail dress or fancy pantsuit, while gem-set and gold drop earrings make great daytime accessories.

While there are at least several types of earrings you could be wearing right now, drop earrings work well for anyone who favors a minimalist look. Whatever the occasion, find a wide range of antique, diamond and pearl drop earrings on 1stDibs.
