About this 1.03ct natural cushion diamond

This 1.03ct 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 3375937241. Listed at 19 retailers as of November 4, 2026, with prices from $3,378 to $5,228, a $1,849 spread on the same certified stone. Washington Diamond lists it at $5,228. 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.
