About this 4.02ct lab-grown radiant diamond

This 4.02ct lab-grown radiant sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG680570997 or 680570997. Listed at 26 retailers as of October 29, 2026, with prices from €2,826 to €12,549, a €9,723 spread on the same certified stone. Brilliant Earth lists it at €12,549. 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.
