About this 1.02ct lab-grown radiant diamond

This 1.02ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836608130 or 836608130. Listed at 9 retailers as of October 28, 2026, with prices from £250 to £1,614, a £1,364 spread on the same certified stone. Brilliant Earth lists it at £1,614. 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.
