About this 1.51ct natural princess diamond

This 1.51ct 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 2221029367. Listed at 19 retailers as of October 30, 2026, with prices from $13,143 to $29,478, a $16,335 spread on the same certified stone. NZ Jewellers lists it at $29,478. 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.
