About this 1.01ct natural radiant diamond

This 1.01ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5516368205. Listed at 15 retailers as of November 5, 2026, with prices from £712 to £1,883, a £1,171 spread on the same certified stone. NZ Jewellers lists it at £1,883. 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.
