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 standard cut grade stated by the retailer rather than the lab and certified by GIA 1549672111. Listed at 18 retailers as of November 4, 2026, with prices from $2,253 to $5,284, a $3,031 spread on the same certified stone. MOH London lists it at $5,284. 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.
