About this 1.21ct natural princess diamond

This 1.21ct natural princess sits in the classic one-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 5566714385. Listed at 9 retailers as of November 1, 2026, with prices from €1,629 to €2,948, a €1,319 spread on the same certified stone. Helzberg Diamonds lists it at €2,948. 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.
