About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2568434992. Listed at 12 retailers as of November 5, 2026, with prices from £1,721 to £3,898, a £2,177 spread on the same certified stone. NZ Jewellers lists it at £3,898. 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.
