This 1.22ct lab-grown radiant 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 LG578341098 or 578341098. Listed at 21 retailers as of November 1, 2026, with prices from €580 to €2,785, a €2,206 spread on the same certified stone. MOH London lists it at €2,785. 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.
