This 3.08ct 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 LG754595426 or 754595426. Listed at 27 retailers as of November 4, 2026, with prices from $5,633 to $25,793, a $20,160 spread on the same certified stone. With Clarity lists it at $25,793. 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.
