Questions About 4ct Diamond Solitaire
  • 1stDibs ExpertSeptember 28, 2021
    The best setting for a solitaire diamond is the prong setting. In such a setting, the stone is held in place with a minimal amount of metal allowing more light to pass through the diamond resulting in added brilliance. Find a collection of solitaire diamond jewelry on 1stDibs.
  • 1stDibs ExpertSeptember 28, 2021
    A 4-carat diamond’s worth varies depending on the 4Cs of diamond quality – color, cut, clarity and carat. On average, a 4-carat diamond could cost you between $8,400 to $71,500. It is also likely that the price range per carat will be even broader. On 1stDibs, you can find a variety of 4-carat diamond jewelry.
  • 1stDibs ExpertFebruary 22, 2021
    A 4 prong makes a diamond look larger than a 6 prong because there is less of the stone's surface covered up by the prongs. 4 prong mounting also allows for more light to fall onto the stone.
