About this 1.31ct natural oval diamond

This 1.31ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 756554855. Listed at 7 retailers as of October 30, 2026, with prices from £1,577 to £3,687, a £2,110 spread on the same certified stone. NZ Jewellers lists it at £3,687. 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.
