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 LG844617817 or 844617817. Listed at 14 retailers as of November 3, 2026, with prices from $4,250 to $15,346, a $11,096 spread on the same certified stone. Taylor and Hart lists it at $15,346. 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.
