About this 1.5ct natural princess diamond

This 1.5ct natural princess sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1155317426. Listed at 17 retailers as of October 25, 2026, with prices from $15,250 to $28,556, a $13,306 spread on the same certified stone. NZ Jewellers lists it at $28,556. 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.
