About this 1ct natural princess diamond

This 1ct natural princess sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 457048360. Listed at 11 retailers as of November 4, 2026, with prices from £1,270 to £3,400, a £2,130 spread on the same certified stone. NZ Jewellers lists it at £3,400. 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.
