About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 800655117. Listed at 14 retailers as of October 30, 2026, with prices from £2,280 to £4,475, a £2,195 spread on the same certified stone. NZ Jewellers lists it at £4,475. 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.
