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 November 2, 2026, with prices from $1,662 to $10,433, a $8,771 spread on the same certified stone. Brilliant Earth lists it at $10,433. 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.
