Questions About Certified Sapphire Diamond
  • 1stDibs ExpertFebruary 22, 2021
    Whether or not you decide to buy certified diamonds is totally your choice, as certified diamonds aren't necessarily better than non-certified ones. However, people tend to gravitate towards certified diamonds because retailers prefer to sell them, which, in turn, promises a specific quality.
  • 1stDibs ExpertApril 5, 2022
    Yes, Cartier diamonds are indeed GIA certified. The Gemological Institute of America (GIA) works closely with Cartier and certifies everything from the cut and clarity to the color of the gem. Shop a collection of expertly vetted Cartier jewelry from some of the world’s top sellers on 1stDibs.
  • 1stDibs ExpertAugust 17, 2021
    In the United States, diamond rings are certified by an official gemological laboratory known as the Gemological Institute of America. A certified diamond ring means that the diamond has undergone a quality analysis by experts at an institution such as the GIA and these experts have issued a lab report that is indicative of the grading process.
  • 1stDibs ExpertFebruary 22, 2021
    When a diamond is GIA certified, it means that the stone has undergone the meticulous set of grading procedures that have been established by the Gemological Institute of America. The GIA is not a jeweler — it is an independent, nonprofit group that sets the standards for determining the quality of a diamond.
  • 1stDibs ExpertFebruary 13, 2023
    While diamond studs don't need to be GIA-certified to be sold, experts typically recommend that you only purchase diamonds that carry certification from the Gemological Institute of America (GIA) or Authentic Gem Security Lab (AGSL). Certifications bring transparency to the buying process, allowing you to know the level of quality of a diamond before you purchase it. Shop a collection of vintage and modern diamond gemstone earrings from some of the world’s top jewelers on 1stDibs.
  • 1stDibs ExpertMarch 22, 2022
    Whether Neil Lane diamonds are GIA-certified or not depends on the piece. All of the diamonds featured in rings and other jewelry designs from the Neil Lane Couture collection do carry GIA certification. Pieces made for third-party retailers may not. On 1stDibs, find a collection of Neil Lane jewelry.
  • 1stDibs ExpertFebruary 22, 2021
    Unless the sapphire is much bigger, a diamond is typically more expensive because it's rarer and harder.
  • 1stDibs ExpertApril 5, 2022
    No, sapphire diamonds are not real diamonds. They are actually white or colorless sapphire gemstones. Diamonds are pure carbon, while sapphires are corundum minerals that contain aluminum oxide and trace elements. On 1stDibs, find a large selection of expertly vetted diamond gemstone jewelry.
  • 1stDibs ExpertOctober 19, 2021
    A white sapphire is any gem-quality corundum that is either white or colorless. With a few exceptions, a white sapphire looks remarkably similar to a diamond in terms of cut and color. Diamonds will always appear brighter and have more colorful flashes than sapphires. Both diamonds and sapphires are hard and will resist everyday scratches. On 1stDibs, find antique and vintage diamond jewelry and white sapphire jewelry today.
  • 1stDibs ExpertDecember 4, 2023
    Yes, white sapphires look like diamonds. However, their appearances aren't completely identical. Although both are white or clear gemstones, the sparkle of a white sapphire will usually appear silvery or gray in color, while diamonds have a rainbow-colored sparkle due to how light interacts with them. Shop a wide range of white sapphire and diamond jewelry on 1stDibs.
