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 SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 743535493. Listed at 16 retailers as of October 30, 2026, with prices from $3,437 to $8,021, a $4,584 spread on the same certified stone. NZ Jewellers lists it at $8,021. 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.
