About this 2.18ct lab-grown radiant diamond

This 2.18ct lab-grown radiant sits in the two to three carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG768631667 or 768631667. Listed at 14 retailers, with prices from $668 to $4,960 at Brilliant Earth, a $4,292 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.
