About this 1.5ct natural princess diamond

This 1.5ct 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 2151733322. Listed at 22 retailers as of November 1, 2026, with prices from $12,342 to $23,159, a $10,817 spread on the same certified stone. NZ Jewellers lists it at $23,159. 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.
