About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2544781019. Listed at 20 retailers as of November 7, 2026, with prices from $3,356 to $7,497, a $4,141 spread on the same certified stone. MOH London lists it at $7,497. 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.
