This 3.09ct 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 LG833657400 or 833657400. Listed at 10 retailers as of November 2, 2026, with prices from $4,550 to $15,443, a $10,893 spread on the same certified stone. Taylor and Hart lists it at $15,443. 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.
