About this 1.04ct natural radiant diamond

This 1.04ct natural radiant sits in the classic one-carat band, graded H 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 6451008679. Listed at 12 retailers as of October 28, 2026, with prices from £1,157 to £3,486, a £2,329 spread on the same certified stone. NZ Jewellers lists it at £3,486. 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.
