About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1232795259. Listed at 12 retailers as of November 6, 2026, with prices from $5,656 to $11,240, a $5,584 spread on the same certified stone. MOH London lists it at $11,240. 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.
