About this 1.31ct natural princess diamond

This 1.31ct natural princess sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1383100678. Listed at 10 retailers as of November 6, 2026, with prices from €3,412 to €5,989, a €2,576 spread on the same certified stone. Wholesale Diamonds Direct lists it at €5,989. 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.
