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 October 30, 2026, with prices from €379 to €1,758, a €1,379 spread on the same certified stone. Brilliance lists it at €1,758. 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.
