About this 4.06ct lab-grown radiant diamond

This 4.06ct 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 LG631407023 or 631407023. Listed at 20 retailers, with prices from $2,230 to $8,540 at Brilliant Earth, a $6,310 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.
