This 1.29ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG787621251 or 787621251. Listed at 12 retailers as of November 3, 2026, with prices from $654 to $3,600, a $2,945 spread on the same certified stone. MOH London lists it at $3,600. 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.
