About this 4ct lab-grown marquise diamond

This 4ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG737563384 or 737563384. Listed at 20 retailers as of October 31, 2026, with prices from $7,701 to $32,627, a $24,926 spread on the same certified stone. Taylor and Hart lists it at $32,627. 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.
