About this 1.02ct lab-grown marquise diamond

This 1.02ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818653983 or 818653983. Listed at 8 retailers as of October 28, 2026, with prices from $619 to $2,771, a $2,153 spread on the same certified stone. Rare Carat lists it at $2,771. 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.
