About this 0.9ct lab-grown radiant diamond

This 0.9ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG605380278 or 605380278. Listed at 8 retailers, with prices from $359 to $1,195 at Rare Carat, a $836 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.
