About this 4.23ct lab-grown radiant diamond

This 4.23ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1523307724. Listed at 11 retailers, with prices from $16,420 to $38,684 at MOH London, a $22,264 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.
