About this 3.09ct lab-grown marquise diamond

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 LG762544641 or 762544641. Listed at 15 retailers as of October 31, 2026, with prices from $3,593 to $18,013, a $14,420 spread on the same certified stone. Taylor and Hart lists it at $18,013. 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.
