About this 1.01ct natural round diamond

This 1.01ct natural round sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 2237644173. Listed at 24 retailers as of October 30, 2026, with prices from £1,655 to £3,950, a £2,295 spread on the same certified stone. NZ Jewellers lists it at £3,950. 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.
