About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6412280875. Listed at 15 retailers as of October 30, 2026, with prices from £1,022 to £3,079, a £2,057 spread on the same certified stone. NZ Jewellers lists it at £3,079. 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.
