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 Royal Blue Diamond
  • 1stDibs ExpertApril 5, 2022
    Whether or not royal blue and sapphire blue are the same color is largely a matter of personal perception and how the names are used. Generally, both colors describe a deep bright blue. You may see them used generally, but manufacturers of paints, apparel and other items that come in many hues may refer to one blue as royal and another as sapphire.
  • 1stDibs ExpertSeptember 28, 2021
    A good contrast with royal blue white, yellow and green. Shades of Ivory and gold also go well with royal blue. White, yellow, and green are suitable colors to contrast with royal blue. Ivory and gold tones blend well with royal blue as well. On 1stDibs, find a variety of antique and vintage products in various shades to match your décor.
  • 1stDibs ExpertAugust 17, 2021
    Yes, a blue diamond is a real diamond. Contrary to popular belief, diamonds come in an array of colors aside from clear. Blue diamonds are neither color-treated nor enhanced to deliver the icy shade, which can range from a seafoam green to a royal blue.
  • 1stDibs ExpertApril 5, 2022
    Yes, there are blue-green diamonds. However, natural ones are very rare, so most are man-made. The Dresden Green is the most famous example of a genuine blue-green diamond gemstone. You can find a wide selection of diamond gemstone jewelry on 1stDibs.
  • 1stDibs ExpertFebruary 22, 2021
    A light blue 0.5 carat diamond is worth roughly $26,280 on average. A deep blue 0.25 diamond, costs $75,000 on average. Blue diamonds are the rarest color of diamond, only found in three areas of the world: Australia, South Africa, and India. The deeper the blue diamonds are even more rare and therefore more expensive.
  • 1stDibs ExpertAugust 26, 2024
    Yes, Blue Nile diamonds are real diamonds. The luxury jewelry maker uses natural diamonds ethically sourced from mines for many of its pieces. In addition, Blue Nile offers an assortment of lab-created diamond rings, earrings, necklaces and bracelets. Lab-created diamonds are still real, but they are human-made rather than mined. On 1stDibs, find an assortment of Blue Nile diamond jewelry.
  • 1stDibs ExpertAugust 29, 2024
    To tell if your blue diamond is real, look for a maker's mark on your piece. By researching the manufacturer using trusted online resources, you can find out if the jewelry maker tends to use authentic gemstones or rhinestones in its pieces. If you can't find a mark or are still uncertain, consult a certified appraiser or knowledgeable jeweler. Performing home tests for diamond authenticity can damage your jewelry, so getting a professional opinion is often the best way to protect your piece. Find a range of blue diamond jewelry on 1stDibs.
  • 1stDibs ExpertSeptember 16, 2024
    Yes, blue diamonds may be worth something. How much a particular gemstone is worth depends on its color, cut, clarity and size, measured in carats. Generally, naturally occurring blue diamonds are worth more than human-made synthetic ones. A certified appraiser or knowledgeable jeweler can inspect your loose gemstone or diamond jewelry and provide you with its estimated value. Explore a diverse assortment of blue diamond jewelry on 1stDibs.
  • 1stDibs ExpertApril 22, 2024
    Yes, Blue Nile diamonds are legit. The jewelry maker offers both natural diamonds sourced from mines and lab-created diamonds produced via controlled scientific techniques. Both types of diamonds are legitimate or genuine gemstones. Find a range of Blue Nile diamond jewelry on 1stDibs.
  • 1stDibs ExpertOctober 5, 2021
    The price of a natural blue diamond is determined first by the color and then its clarity. Depending on these factors and the size chosen, there is a huge variation in price. You will find the blue diamond price range from under $2,000 to over $10,000 on 1stDibs.
  • 1stDibs ExpertOctober 5, 2021
    A blue diamond ring worth depends on the type of blue diamond. Ideally, a blue diamond’s cost is based on its 4Cs (cut, color, clarity, and carat), with the intensity of the color being the dominant factor. A blue diamond ring price ranges between $6,800 to $11,200. On 1stDibs, you can find a range of exquisite antique and vintage blue diamond rings.
  • 1stDibs ExpertMay 30, 2024
    Yes, Blue Nile sells real diamonds. Many of the jewelry maker's pieces feature natural diamonds. Others are set with lab-created diamonds, which are real but are the result of processes performed in laboratories. On 1stDibs, explore a collection of Blue Nile diamond jewelry from some of the world's top sellers.
  • 1stDibs ExpertSeptember 16, 2024
    How much a 1-carat blue diamond is worth depends on its cut, clarity and color. Human-made synthetic blue diamonds of that size are often worth less than $10,000, while natural examples sourced through mining are generally valued at much higher prices. If a gemstone is set in a piece of jewelry, it may have additional value due to the precious metals, the maker of the piece, its age and other factors. Because so many variables can impact the potential value of a blue diamond, experts generally recommend having a certified appraiser or experienced jeweler assist with the valuation process. On 1stDibs, explore a diverse assortment of blue diamond jewelry.
