About this 1.02ct natural round diamond

This 1.02ct natural round sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 3415214529. Listed at 18 retailers as of October 31, 2026, with prices from £1,389 to £3,998, a £2,609 spread on the same certified stone. NZ Jewellers lists it at £3,998. 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.
