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 Triangle Cut Diamond
  • 1stDibs ExpertFebruary 22, 2021
    A triangle shaped diamond is called a Triangular brilliant or a Trilliant or Trillion. They are cut so that there are three equally straight sides and are often cut from shallow double crystals.
  • 1stDibs ExpertNovember 8, 2023
    Yes, the princess cut is a good cut for a diamond. For one thing, princess-cut diamonds are similar to the shape of a raw diamond. As a result, jewelers waste less of the stone, often leading to cost-effective pricing for princess-cut diamond jewelry. The princess cut is also visually appealing due to its symmetrical shape. As a brilliant cut, it shows off the sparkle of a diamond. On 1stDibs, shop a collection of princess-cut diamond jewelry.
  • 1stDibs ExpertOctober 12, 2021
    A French cut diamond is a diamond that is cut in a square or rectangular shape, and features a high crown, along with triangle-shaped facets in a crisscross pattern. A French cut diamond is made by grinding the top of the crystal gemstone. Find a collection of antique, vintage and new French cut diamond jewelry on 1stDibs today.
  • 1stDibs ExpertNovember 2, 2021
    A Victorian-cut diamond features a top crown that is distinctly multifaceted — it has a small table and step-cut bottom pavilion that comprises 73 facets. It appears quite large when set. Relatedly, rose-cut diamonds are uncommon in modern jewelry and are often associated with antique styles like Victorian or Georgian.
  • 1stDibs ExpertMarch 22, 2022
    A cushion cut diamond is one that has a square shape with rounded corners. It differs from the similarly shaped emerald cut in that it has a brilliant cut that maximizes sparkle rather than a stepped cut that shows off color and clarity. You'll find a variety of cushion cut diamond jewelry on 1stDibs.
  • 1stDibs ExpertNovember 8, 2023
    Generally, the most expensive cut of diamond is the brilliant round cut. This cut creates the most waste during the shaping process, and the excess material gets factored into the price.
