About this 2.55ct lab-grown marquise diamond

This 2.55ct lab-grown marquise sits in the two to three carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818655644 or 818655644. Listed at 13 retailers as of November 2, 2026, with prices from $6,141 to $26,505, a $20,364 spread on the same certified stone. With Clarity lists it at $26,505. 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.
