About this 1.03ct natural round diamond

This 1.03ct natural round sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 523201896. Listed at 15 retailers as of October 30, 2026, with prices from £1,265 to £3,386, a £2,121 spread on the same certified stone. NZ Jewellers lists it at £3,386. 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.
