About this 1ct natural cushion diamond

This 1ct 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 7418531106. Listed at 18 retailers as of November 4, 2026, with prices from $2,853 to $6,824, a $3,972 spread on the same certified stone. MOH London lists it at $6,824. 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.
