About this 3ct lab-grown marquise diamond

This 3ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG839641052 or 839641052. Listed at 23 retailers as of November 2, 2026, with prices from $3,607 to $14,600, a $10,993 spread on the same certified stone. Taylor and Hart lists it at $14,600. 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.
