About this 1.02ct natural round diamond

This 1.02ct natural round sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 3555410790. Listed at 21 retailers as of November 2, 2026, with prices from £1,270 to £3,583, a £2,313 spread on the same certified stone. NZ Jewellers lists it at £3,583. 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.
