About this 1.7ct natural princess diamond

This 1.7ct natural princess sits in the one-and-a-half to two carat band, graded I 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 1438966779. Listed at 22 retailers as of October 30, 2026, with prices from $13,399 to $24,112, a $10,713 spread on the same certified stone. NZ Jewellers lists it at $24,112. 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.
