About this 1.51ct natural princess diamond

This 1.51ct natural princess sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 483105789. Listed at 18 retailers as of October 31, 2026, with prices from $8,500 to $19,433, a $10,933 spread on the same certified stone. NZ Jewellers lists it at $19,433. 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.
