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

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

Questions About Octagonal Cut Diamond
  • 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 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. Keep in mind that other factors like clarity, color and carat weight also impact the price. On 1stDibs, find a wide range of diamond jewelry.
  • 1stDibs ExpertJanuary 23, 2024
    A star-cut diamond is a diamond with a certain shape and facet arrangement. Specifically, the style features 86 facets and is a brilliant cut that shows off the sparkle of a diamond. In terms of shape, the cut produces a gemstone that resembles a five-pointed star. On 1stDibs, explore a wide variety of diamond jewelry.
  • 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 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 ExpertNovember 6, 2023
    Diamond cuts on chains are small grooves or notches on the surface of the metal. The addition of this detailing gives metal chains a luminous, almost sparkling effect. The term is not to be confused with diamond cut, which refers to the design guide that a jeweler uses for shaping gemstones. A diamond's cut relates to how well the stone's facets interact with light. Explore a variety of chain necklaces on 1stDibs.
  • 1stDibs ExpertNovember 21, 2023
    A Peruzzi-cut diamond is a diamond cut in a particular shape. It features rounded edges and a third row of rhomboidal and triangular crown facets compared to the brilliant round cut. To create the Peruzzi cut, a maker produces 58 brilliant facets, also known as the triple cut. Venetian jeweler Vincenzo Peruzzi developed the cut during the 17th century. On 1stDibs, find a large collection of diamond jewelry.
  • 1stDibs ExpertJanuary 23, 2024
    A Poor cut diamond is a diamond with a specific cut rating from the Gemological Institute of America (GIA). Cut refers to the arrangement of facets on a diamond, and GIA rates cuts on a scale from Excellent to Poor. The Poor cut will have little to no sparkle or brilliance, usually due to imperfections in the placement of its facets. Shop a diverse assortment of diamond jewelry on 1stDibs.
  • 1stDibs ExpertFebruary 22, 2021
    A rose cut diamond boasts a cabbed flat base and a faceted top. It is called a rose cut diamond because it resembles the shape of a rose.
  • 1stDibs ExpertApril 5, 2022
    Shield cut diamonds have a triangular shape with three sides bowed so the diamond sort of resembles a shield. They’re often used in rings as side accents to the center stone, so they rest a large side against the stone and then taper down the band. Shop a collection of authentic shield cut diamonds from some of the world’s top boutiques on 1stDibs.
  • 1stDibs ExpertFebruary 22, 2021
    European cut diamonds were most popular from the late 19th century to the mid-20th century. They're quite brilliant in terms of shine quality and feature a large culet,small table and round shape.
  • 1stDibs ExpertFebruary 22, 2021
    A mine cut diamond is an antique diamond cut known for its bulky and often uneven shape, cutlet, and tiny table. This type of diamond cut was quite popular in the mid-1800s to the early-1900s
    Mine cut diamonds are typically called OLD MINE CUTS, This type of cutting started in the early 1700s. The shapes are typically cushion shape and the cutting was done all by hand. Though they do not have the sparkle of modern cut diamonds, when they sparkle in sunlight or candle light, they have this beautiful alluring shimmer.
  • 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.

  • 1stDibs ExpertFebruary 22, 2021
    The most popular diamond cut is round brilliant with fifty seven perfectly aligned facets. Other popular cuts include cushion cut diamond, princess cut diamond and emerald cut diamond.
  • 1stDibs ExpertNovember 21, 2023
    The cut that is best for a diamond depends on your individual preferences. If you love the sparkle of diamonds, a brilliant cut like the brilliant round, princess, marquise, oval or pear may be ideal. If you want to show off the clarity and color of a diamond, you may prefer stepped cuts like the emerald, Asscher, baguette or carré. In terms of Gemological Institute of America (GIA) ratings, the best diamond cuts are those that carry an excellent grade. Find a large collection of diamond jewelry on 1stDibs.
  • 1stDibs ExpertJanuary 23, 2024
    The term diamond cuts means how a jeweler prepares a raw diamond for a piece of jewelry. Using tools, jewelers create flat surfaces called facets, and the arrangement and number of these facets affect the shape and appearance of the finished gem. Examples of diamond cuts include the brilliant round, the emerald, the oval and the cushion. Explore a wide range of diamond jewelry on 1stDibs.
