About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6372933941. Listed at 16 retailers as of November 5, 2026, with prices from $2,778 to $4,259, a $1,480 spread on the same certified stone. Washington Diamond lists it at $4,259. 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.
