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 SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 7452395184. Listed at 14 retailers as of November 5, 2026, with prices from £1,308 to £3,533, a £2,225 spread on the same certified stone. NZ Jewellers lists it at £3,533. 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.
