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.

- How big is a 2 carat emerald?1 Answer1stDibs ExpertFebruary 22, 2021A two carat emerald is 8.5 x 6.0mm. Because emeralds are quite strong they can be great for everyday wear.
- 1stDibs ExpertNovember 1, 2023Whether two-carat diamond studs are too big is a matter of personal preference. At this size, each earring will be one carat. If you opt for the classic round brilliant cut, the studs will typically measure around 6.5 millimeters in diameter, which is a little more than half the size of a dime. Find a wide range of diamond stud earrings on 1stDibs.
- 1stDibs ExpertAugust 24, 2021A 2 carat oval diamond is approximately 10.23mm × 6.82mm × 4.16mm in size. These diamonds usually have an approximate face-up area of 57.21 mm². Find a variety of diamonds on 1stDibs.
- 1stDibs ExpertNovember 8, 2023How big a 2-carat diamond with a princess cut is varies from piece to piece. However, the average size is 7 millimeters by 7 millimeters. The measurement is around 9/32 inches, so a 2-carat princess-cut diamond will be just a little over a quarter-inch in size. On 1stDibs, find an assortment of princess-cut diamond jewelry.
- 1stDibs ExpertMarch 3, 2023Whether 2-carat is a good size for an engagement ring is a matter of personal opinion. Due to its size, a 2-carat gemstone will likely stand out and get noticed. However, some people prefer smaller engagement rings, especially if they work with their hands. Carat weight is also not the most important signifier of a stone’s value. A three-carat gem can be less valuable than a one-carat stone, for example, if all of the other attributes are of lesser quality in the larger diamond. On 1stDibs, shop a collection of engagement rings.
