About this 3.49ct lab-grown radiant diamond

This 3.49ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI. Listed at 2 retailers, with prices from $2,295 to $10,825 at Blue Nile, a $8,530 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.
