About this 1.22ct lab-grown marquise diamond

This 1.22ct lab-grown marquise sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG800677372 or 800677372. Listed at 14 retailers as of October 30, 2026, with prices from €257 to €2,282, a €2,026 spread on the same certified stone. Do Amore Diamonds lists it at €2,282. 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.
