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 VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 2225809517. Listed at 17 retailers as of November 2, 2026, with prices from £2,532 to £5,533, a £3,002 spread on the same certified stone. NZ Jewellers lists it at £5,533. 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.
