    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.

    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 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

  • 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 ExpertOctober 5, 2021
    A blue diamond ring worth depends on the type of blue diamond.

  • 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 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.
