About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1146647770. Listed at 8 retailers as of November 6, 2026, with prices from €3,692 to €4,980, a €1,288 spread on the same certified stone. Jared lists it at €4,980. 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.
