About this 2.57ct lab-grown marquise diamond

This 2.57ct lab-grown marquise sits in the two to three carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG762544476 or 762544476. Listed at 14 retailers as of October 31, 2026, with prices from €2,455 to €12,057, a €9,601 spread on the same certified stone. Taylor and Hart lists it at €12,057. 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.
