About this 1.01ct natural radiant diamond

This 1.01ct natural radiant sits in the classic one-carat band, graded J 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 7328865339. Listed at 16 retailers as of November 5, 2026, with prices from £1,157 to £3,521, a £2,365 spread on the same certified stone. NZ Jewellers lists it at £3,521. 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.
