About this 1.05ct natural cushion diamond

This 1.05ct 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 6127251313. Listed at 4 retailers as of November 1, 2026, with prices from $4,159 to $8,566, a $4,407 spread on the same certified stone. MOH London lists it at $8,566. 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.
