About this 1.22ct natural cushion diamond

This 1.22ct 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 2558118541. Listed at 17 retailers as of November 2, 2026, with prices from $1,566 to $3,723, a $2,157 spread on the same certified stone. MOH London lists it at $3,723. 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.
