About this 1.7ct natural princess diamond

This 1.7ct natural princess sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6431899255. Listed at 21 retailers as of October 30, 2026, with prices from $11,646 to $22,277, a $10,631 spread on the same certified stone. NZ Jewellers lists it at $22,277. 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.
