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 rings, vintage engagement rings or Art Deco engagement rings. 

Shop antique and vintage diamond rings, diamond necklaces and other extraordinary diamond jewelry on 1stDibs.  

Questions About Gia Red Diamond

  • 1stDibs ExpertAugust 20, 2024
    Yes, in many cases, GIA diamonds are worth more. To gain Gemological Institute of America (GIA) certification, a diamond must meet very high standards. As a result, diamonds that carry the certification usually have high color, cut and clarity ratings, making them more valuable than gemstones that can't meet the standards established by the GIA. Also, people may be more willing to pay high prices for GIA-certified diamonds because the certification is a testament to their quality. Shop a large selection of diamond jewelry on 1stDibs.
  • 1stDibs ExpertSeptember 16, 2024
    Yes, many jewelry lovers believe that a GIA diamond is worth it. The Gemological Institute of America (GIA) gives its certification only to diamonds that meet high standards in terms of their color, clarity and cut. Purchasing a GIA-certified diamond can be a way to feel confident about the quality of the gemstone you receive. However, whether or not it’s worth investing in GIA-certified diamonds is totally subjective! At 1stDibs, we believe in buying what you love. Our shopping experience enables discovery and learning, whether you are a seasoned connoisseur or just beginning your collection. On 1stDibs, shop a wide range of diamond jewelry from some of the world's top sellers.

    Yes, Cartier diamonds are indeed GIA certified. The Gemological Institute of America (GIA) works closely with Cartier and certifies everything from the cut and clarity to the color of the gem. Shop a collection of expertly vetted Cartier jewelry from some of the world’s top sellers on 1stDibs.
  • 1stDibs ExpertFebruary 22, 2021
    When a diamond is GIA certified, it means that the stone has undergone the meticulous set of grading procedures that have been established by the Gemological Institute of America. The GIA is not a jeweler — it is an independent, nonprofit group that sets the standards for determining the quality of a diamond.
  • 1stDibs ExpertAugust 17, 2021
    In the United States, diamond rings are certified by an official gemological laboratory known as the Gemological Institute of America. A certified diamond ring means that the diamond has undergone a quality analysis by experts at an institution such as the GIA and these experts have issued a lab report that is indicative of the grading process.
  • 1stDibs ExpertOctober 7, 2024
    GIA diamonds are real. The Gemological Institute of America, or GIA, only certifies real diamonds that meet the organization's cut, clarity and color standards. Both naturally mined diamonds and human-made lab-created diamonds can be GIA-certified. On 1stDibs, shop a wide variety of diamond jewelry from some of the world's top sellers.
  • 1stDibs ExpertFebruary 13, 2023
    While diamond studs don't need to be GIA-certified to be sold, experts typically recommend that you only purchase diamonds that carry certification from the Gemological Institute of America (GIA) or Authentic Gem Security Lab (AGSL). Certifications bring transparency to the buying process, allowing you to know the level of quality of a diamond before you purchase it. Shop a collection of vintage and modern diamond gemstone earrings from some of the world’s top jewelers on 1stDibs.
  • 1stDibs ExpertMarch 22, 2022
    Whether Neil Lane diamonds are GIA-certified or not depends on the piece. All of the diamonds featured in rings and other jewelry designs from the Neil Lane Couture collection do carry GIA certification. Pieces made for third-party retailers may not. On 1stDibs, find a collection of Neil Lane jewelry.
  • 1stDibs ExpertAugust 15, 2024
    Many experts believe that buying a GIA-certified diamond is worth it. The Gemological Institute of America (GIA) has a well-established reputation for providing accurate, trustworthy ratings and certifications. A diamond that carries a GIA certification has undergone rigorous examinations and tests to assess its quality, which can make it a good investment. Find a diverse assortment of diamond jewelry on 1stDibs.
