Questions About 18 Carat Sapphire
  • 1stDibs ExpertApril 5, 2022
    The highest carat sapphire to ever be discovered is the Blue Giant of the Orient, as of January 2022. It weighs 486.52 carats and originated from a mine in Ratnapura, Sri Lanka. On 1stDibs, shop a large selection of sapphire gemstone jewelry.
  • 1stDibs ExpertFebruary 22, 2021
    A standard size of a round sapphire is 6mm which is approximately one carat, making 7mm sapphires just slightly larger than a carat. Because sapphires are heavier than diamonds, a one carat sapphire is slightly smaller than a one carat diamond.
  • 1stDibs ExpertMay 5, 2023
    How much a 1-carat natural sapphire is worth depends on its color, cut and quality. Sapphires can range in value from $25 to thousands of dollars per carat. A certified appraiser or knowledgeable jewelry expert can examine a particular gemstone piece and give you an estimate of its value. On 1stDibs, find a collection of sapphire gemstone jewelry.
