About this 1.02ct natural round diamond

This 1.02ct natural round sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 7431574069. Listed at 16 retailers as of November 5, 2026, with prices from £1,312 to £3,237, a £1,925 spread on the same certified stone. NZ Jewellers lists it at £3,237. 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.
