This 1.34ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG789612866 or 789612866. Listed at 27 retailers as of November 4, 2026, with prices from €279 to €2,085, a €1,806 spread on the same certified stone. Do Amore Diamonds lists it at €2,085. 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.
