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 25 retailers as of October 23, 2026, with prices from $5,437 to $24,963, a $19,526 spread on the same certified stone. Brilliant Earth lists it at $24,963. 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.
