About this 1ct natural princess diamond

This 1ct natural princess sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1242097443. Listed at 12 retailers as of October 29, 2026, with prices from €1,447 to €2,668, a €1,221 spread on the same certified stone. Helzberg Diamonds lists it at €2,668. 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.
