About this 1.01ct natural round diamond

This 1.01ct natural round sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 2434335798. Listed at 20 retailers as of October 31, 2026, with prices from £1,321 to £3,796, a £2,475 spread on the same certified stone. NZ Jewellers lists it at £3,796. 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.
