About this 1.5ct natural princess diamond

This 1.5ct natural princess sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 530201832. Listed at 11 retailers as of November 4, 2026, with prices from £1,358 to £3,144, a £1,785 spread on the same certified stone. NZ Jewellers lists it at £3,144. 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.
