About this 1.59ct lab-grown radiant diamond

This 1.59ct 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 very-good cut grade and certified by IGI LG660484617 or 660484617. Listed at 26 retailers, with prices from $336 to $2,610 at Rare Carat, a $2,274 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.
