This 3.07ct 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 LG754594983 or 754594983. Listed at 27 retailers as of November 2, 2026, with prices from $4,329 to $19,948, a $15,619 spread on the same certified stone. With Clarity lists it at $19,948. 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.
