This 1.2ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG836626484 or 836626484. Listed at 12 retailers as of October 30, 2026, with prices from €186 to €1,028, a €842 spread on the same certified stone. Reve Diamonds lists it at €1,028. 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.
