About this 2.54ct lab-grown radiant diamond

This 2.54ct lab-grown radiant sits in the two to three carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG818684285 or 818684285. Listed at 12 retailers as of October 29, 2026, with prices from £1,229 to £5,135, a £3,906 spread on the same certified stone. Brilliant Earth lists it at £5,135. 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.
