About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6555036647. Listed at 19 retailers as of October 31, 2026, with prices from €2,734 to €5,976, a €3,243 spread on the same certified stone. MOH London lists it at €5,976. 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.
