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 standard cut grade stated by the retailer rather than the lab and certified by GIA 2558490322. Listed at 18 retailers as of November 1, 2026, with prices from $2,509 to $5,879, a $3,370 spread on the same certified stone. MOH London lists it at $5,879. 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.
