About this 1.2ct natural princess diamond

This 1.2ct 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 488152644. Listed at 10 retailers as of November 5, 2026, with prices from $4,908 to $10,439, a $5,531 spread on the same certified stone. NZ Jewellers lists it at $10,439. 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.
