About this 1.02ct natural oval diamond

This 1.02ct natural oval 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 IGI 801639028. Listed at 14 retailers as of October 30, 2026, with prices from £1,165 to £3,117, a £1,952 spread on the same certified stone. NZ Jewellers lists it at £3,117. 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.
