About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1236839340. Listed at 10 retailers as of November 6, 2026, with prices from $4,015 to $5,560, a $1,544 spread on the same certified stone. Washington Diamond lists it at $5,560. 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.
