About this 1.71ct natural princess diamond

This 1.71ct 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 5156929970. Listed at 20 retailers as of October 30, 2026, with prices from $15,860 to $30,005, a $14,145 spread on the same certified stone. NZ Jewellers lists it at $30,005. 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.
