This 3.04ct 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 LG817680803 or 817680803. Listed at 18 retailers as of October 30, 2026, with prices from $4,067 to $16,755, a $12,688 spread on the same certified stone. Taylor and Hart lists it at $16,755. 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.
