This 4.07ct lab-grown marquise sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG764660503 or 764660503. Listed at 25 retailers as of October 30, 2026, with prices from $8,310 to $48,945, a $40,635 spread on the same certified stone. With Clarity lists it at $48,945. 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.
