About this 1.11ct natural cushion diamond

This 1.11ct 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 2151140341. Listed at 2 retailers as of November 5, 2026, with prices from $4,154 to $6,015, a $1,861 spread on the same certified stone. 77 Diamonds lists it at $6,015. 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.
