About this 1.6ct lab-grown radiant diamond

This 1.6ct 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 LG754594272 or 754594272. Listed at 15 retailers, with prices from $336 to $4,750 at Brilliant Earth, a $4,414 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.
