About this 0.81ct lab-grown radiant diamond

This 0.81ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG744510325 or 744510325. Listed at 18 retailers, with prices from $318 to $1,190 at Reve Diamonds, a $872 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.
