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 LG839699095 or 839699095. Listed at 21 retailers as of October 31, 2026, with prices from $4,404 to $18,227, a $13,823 spread on the same certified stone. Taylor and Hart lists it at $18,227. 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.
