About this 1ct natural radiant diamond

This 1ct 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 1565011967. Listed at 17 retailers as of November 5, 2026, with prices from £1,193 to £3,350, a £2,157 spread on the same certified stone. NZ Jewellers lists it at £3,350. 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.
