About this 1.01ct natural round diamond

This 1.01ct 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 6432867704. Listed at 18 retailers as of October 30, 2026, with prices from £1,003 to £3,373, a £2,370 spread on the same certified stone. NZ Jewellers lists it at £3,373. 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.
