About this 1.4ct natural princess diamond

This 1.4ct natural princess sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 621475064. Listed at 10 retailers as of October 30, 2026, with prices from £1,657 to £3,835, a £2,179 spread on the same certified stone. NZ Jewellers lists it at £3,835. 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.
