About this 1.51ct natural princess diamond

This 1.51ct natural princess sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2231015437. Listed at 12 retailers as of October 28, 2026, with prices from $9,899 to $18,985, a $9,086 spread on the same certified stone. NZ Jewellers lists it at $18,985. 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.
