About this 0.77ct natural cushion diamond

This 0.77ct natural cushion sits in the just-under-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 1213428933. Listed at 12 retailers as of November 1, 2026, with prices from $2,954 to $4,649, a $1,694 spread on the same certified stone. Washington Diamond lists it at $4,649. 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.
