This 1.09ct lab-grown radiant 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 LG773639326 or 773639326. Listed at 23 retailers as of October 30, 2026, with prices from €217 to €2,086, a €1,870 spread on the same certified stone. Do Amore Diamonds lists it at €2,086. 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.
