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 20 retailers, with prices from $2,210 to $8,450 at Brilliant Earth, a $6,240 spread on the same certified stone. 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.
