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 VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6421335571. Listed at 25 retailers as of October 30, 2026, with prices from £2,967 to £6,352, a £3,385 spread on the same certified stone. NZ Jewellers lists it at £6,352. 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.
