This 3.03ct lab-grown marquise sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG744510973 or 744510973. Listed at 2 retailers as of October 27, 2026, with prices from $6,512 to $12,806, a $6,294 spread on the same certified stone. Brilliant Earth lists it at $12,806. 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.
