About this 1.35ct lab-grown radiant diamond

This 1.35ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG564354983 or 564354983. Listed at 20 retailers, with prices from $236 to $2,400 at Queensmith, a $2,164 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.
