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 VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 749558771. Listed at 16 retailers as of October 30, 2026, with prices from £1,868 to £4,239, a £2,372 spread on the same certified stone. NZ Jewellers lists it at £4,239. 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.
