About this 1.51ct natural princess diamond

This 1.51ct natural princess sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1403295207. Listed at 23 retailers as of October 30, 2026, with prices from $9,455 to $17,735, a $8,280 spread on the same certified stone. NZ Jewellers lists it at $17,735. 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.
