About this 4.22ct lab-grown radiant diamond

This 4.22ct 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 LG782640813 or 782640813. Listed at 15 retailers, with prices from $2,296 to $15,290 at Brilliant Earth, a $12,994 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.
