About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1447136627. Listed at 8 retailers as of November 4, 2026, with prices from €1,295 to €2,452, a €1,157 spread on the same certified stone. MOH London lists it at €2,452. 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.
