This 3.03ct 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 LG844687276 or 844687276. Listed at 14 retailers as of October 31, 2026, with prices from $2,698 to $9,758, a $7,060 spread on the same certified stone. Taylor and Hart lists it at $9,758. 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.
