This 3.71ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG697509200 or 697509200. Listed at 4 retailers as of October 31, 2026, with prices from €5,524 to €9,479, a €3,955 spread on the same certified stone. Brilliant Earth lists it at €9,479. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
