About this 1.05ct lab-grown marquise diamond

This 1.05ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG717575840 or 717575840. Listed at 17 retailers as of October 30, 2026, with prices from €177 to €1,244, a €1,067 spread on the same certified stone. Brilliant Earth lists it at €1,244. 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.
