About this 2.55ct lab-grown radiant diamond

This 2.55ct lab-grown radiant sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG732559101 or 732559101. Listed at 22 retailers as of October 28, 2026, with prices from $763 to $5,870, a $5,107 spread on the same certified stone. Brilliant Earth lists it at $5,870. 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.
