About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6542331923. Listed at 27 retailers as of October 30, 2026, with prices from £1,656 to £4,375, a £2,719 spread on the same certified stone. NZ Jewellers lists it at £4,375. 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.
