About this 1.03ct natural radiant diamond

This 1.03ct natural radiant sits in the classic one-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI 632408226. Listed at 13 retailers as of November 5, 2026, with prices from £1,325 to £3,720, a £2,395 spread on the same certified stone. NZ Jewellers lists it at £3,720. 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.
