About this 1.31ct natural princess diamond

This 1.31ct natural princess sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 834604992. Listed at 9 retailers as of October 27, 2026, with prices from £1,730 to £4,168, a £2,438 spread on the same certified stone. NZ Jewellers lists it at £4,168. 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.
