About this 1.5ct natural princess diamond

This 1.5ct natural princess sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2151733322. Listed at 21 retailers as of November 1, 2026, with prices from $9,630 to $18,070, a $8,440 spread on the same certified stone. NZ Jewellers lists it at $18,070. 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.
