About this 1.5ct natural princess diamond

This 1.5ct natural princess sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5151363691. Listed at 20 retailers as of October 25, 2026, with prices from $10,835 to $20,481, a $9,646 spread on the same certified stone. NZ Jewellers lists it at $20,481. 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.
