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 standard cut grade and certified by IGI LG700513314 or 700513314. Listed at 25 retailers, with prices from $357 to $2,620 at Rare Carat, a $2,263 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.
