This 1.01ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG750529676 or 750529676. Listed at 2 retailers as of November 2, 2026, with prices from €479 to €580, a €101 spread on the same certified stone. Brilliant Earth lists it at €580. 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.
