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 November 2, 2026, with prices from $3,066 to $6,703, a $3,637 spread on the same certified stone. MOH London lists it at $6,703. 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.
