About this 1.01ct natural cushion diamond

This 1.01ct 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 1378934020. Listed at 16 retailers as of November 6, 2026, with prices from $2,466 to $3,787, a $1,321 spread on the same certified stone. Washington Diamond lists it at $3,787. 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.
