About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6405677842. Listed at 12 retailers as of November 6, 2026, with prices from €722 to €1,285, a €563 spread on the same certified stone. Yorxs lists it at €1,285. 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.
