About this 1.29ct natural princess diamond

This 1.29ct natural princess sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5231587323. Listed at 9 retailers as of November 1, 2026, with prices from €2,987 to €4,262, a €1,275 spread on the same certified stone. Washington Diamond lists it at €4,262. 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.
