About this 1.5ct natural princess diamond

This 1.5ct natural princess sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2516840610. Listed at 16 retailers as of November 1, 2026, with prices from $11,572 to $21,001, a $9,429 spread on the same certified stone. NZ Jewellers lists it at $21,001. 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.
