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 IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG595389145 or 595389145. Listed at 22 retailers as of October 27, 2026, with prices from £161 to £931, a £770 spread on the same certified stone. Reve Diamonds lists it at £931. 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.
