About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded G 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 2556749371. Listed at 14 retailers as of November 4, 2026, with prices from $2,548 to $5,978, a $3,430 spread on the same certified stone. MOH London lists it at $5,978. 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.
