About this 3.51ct lab-grown radiant diamond

This 3.51ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG762544413 or 762544413. Listed at 15 retailers, with prices from $2,925 to $11,660 at Brilliant Earth, a $8,735 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.
