About this 1.05ct natural radiant diamond

This 1.05ct 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 6452147309. Listed at 12 retailers as of October 28, 2026, with prices from £1,162 to £3,514, a £2,351 spread on the same certified stone. NZ Jewellers lists it at £3,514. 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.
