About this 1.01ct lab-grown marquise diamond

This 1.01ct 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 LG780665307 or 780665307. Listed at 14 retailers as of October 28, 2026, with prices from $224 to $2,506, a $2,282 spread on the same certified stone. Rare Carat lists it at $2,506. 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.
