This 1.54ct lab-grown marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831606460 or 831606460. Listed at 18 retailers as of November 4, 2026, with prices from €377 to €1,750, a €1,373 spread on the same certified stone. Brilliance lists it at €1,750. 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.
