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 standard cut grade and certified by IGI. Listed at 6 retailers, with prices from $375 to $1,652 at NZ Jewellers, a $1,277 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.
