About this 1.22ct natural radiant diamond

This 1.22ct natural radiant sits in the classic one-carat band, graded E 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 6551558744. Listed at 12 retailers as of November 4, 2026, with prices from €2,782 to €5,292, a €2,510 spread on the same certified stone. Helzberg Diamonds lists it at €5,292. 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.
