About this 2.51ct lab-grown radiant diamond

This 2.51ct lab-grown radiant sits in the two to three carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825659727 or 825659727. Listed at 9 retailers as of October 29, 2026, with prices from $2,475 to $11,212, a $8,737 spread on the same certified stone. Brilliant Earth lists it at $11,212. 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.
