The Legacy of Diamond in Jewelry Design

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 ringsvintage engagement rings or Art Deco engagement rings

Questions About Black Diamond Cabochon
  • 1stDibs ExpertApril 5, 2022
    Yes, a black diamond is indeed a real diamond. There are three types of black diamonds; natural, Carbonado and treated black diamonds. Treated black diamonds are altered with high pressure and high heat to achieve the black color. Shop a collection of expertly vetted gems from some of the world’s top sellers on 1stDibs.
  • 1stDibs ExpertFebruary 22, 2021
    Yes, a black diamond is a real diamond. Black diamonds have the same chemical composition as traditional colorless diamonds. Although black diamonds are rarer than colorless diamonds, they are less coveted and therefore cheaper.
  • 1stDibs ExpertOctober 12, 2021
    Black diamonds are said to have a deep spiritual connotation and are frequently used to ward off evil. The gorgeous dark gemstone is thought to offer a link between the spiritual and physical worlds. Diamonds, in general, represent a deep emotional bond, which is why they are ideal for engagement rings. On 1stDibs, find a variety of black diamond jewelry and watches.
  • 1stDibs ExpertAugust 26, 2024
    The difference between a black diamond and a black sapphire is that the two are different gemstones. A black diamond consists of carbon converted to a crystalline solid through changes driven by pressure and temperature. A black sapphire is a type of corundum, an aluminum oxide mineral. Generally, black diamonds are harder, rarer and more expensive than black sapphires. On 1stDibs, shop an assortment of black diamond and sapphire jewelry.
  • 1stDibs ExpertSeptember 9, 2024
    Yes, black diamonds are generally worth something. The specific value of a genuine black diamond depends on its size, measured in carats, as well as its color, cut and clarity. If you own a black diamond or a piece set with one, a certified appraiser or knowledgeable jeweler can give you an idea of how much it may be worth. Shop a variety of black diamond jewelry on 1stDibs.
  • 1stDibs ExpertFebruary 22, 2021
    White, or colorless, diamonds are generally the most valuable diamond variety. Black diamonds are certainly more rare than white ones, but the latter is generally more expensive.
  • 1stDibs ExpertApril 5, 2022
    What black diamond rings symbolize is largely a matter of personal interpretation. Charisma, power, passion and self-assuredness are some of the characteristics commonly associated with black diamond jewelry. Shop a range of diamond gemstone rings from top sellers around the world on 1stDibs.

    Black diamond engagement rings are popular for many couples. An antique, new or vintage black diamond engagement ring is an edgy, dramatic choice. Just keep in mind that with diamonds, it's all about sparkle, and the darkness of a black stone obscures its fire and brilliance. If the inky opacity of a black diamond seems a bit extreme and you'd like a little light to shine through, consider a gray diamond, which can be cut for maximum brilliance. Brides with a taste for the cool and unusual might also consider salt-and-pepper diamonds, which have white and black inclusions that produce a silvery gray, speckled look.
