About this 1.21ct lab-grown radiant diamond

This 1.21ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG799649696 or 799649696. Listed at 25 retailers as of November 2, 2026, with prices from €240 to €1,721, a €1,481 spread on the same certified stone. Brilliant Earth lists it at €1,721. 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.
