About this 1.5ct natural princess diamond

This 1.5ct natural princess sits in the one-and-a-half to two carat band, graded H 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 1439137203. Listed at 17 retailers as of October 30, 2026, with prices from $6,130 to $12,977, a $6,847 spread on the same certified stone. NZ Jewellers lists it at $12,977. 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.
