About this 1.6ct lab-grown radiant diamond

This 1.6ct lab-grown radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG768631244 or 768631244. Listed at 11 retailers, with prices from $450 to $3,800 at Brilliant Earth, a $3,350 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.
