About this 1.01ct natural radiant diamond

This 1.01ct natural radiant sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3545195873. Listed at 17 retailers as of November 5, 2026, with prices from £1,270 to £3,564, a £2,294 spread on the same certified stone. NZ Jewellers lists it at £3,564. 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.
