About this 4.03ct lab-grown marquise diamond

This 4.03ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG773639183 or 773639183. Listed at 21 retailers as of October 31, 2026, with prices from $11,304 to $51,670, a $40,367 spread on the same certified stone. Frank Darling lists it at $51,670. 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.
