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 €157 to €1,754, a €1,598 spread on the same certified stone. Rare Carat lists it at €1,754. 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.
