About this 1.05ct natural cushion diamond

This 1.05ct 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 2245044151. Listed at 22 retailers as of October 31, 2026, with prices from $1,483 to $6,677, a $5,194 spread on the same certified stone. Diamond Quarter lists it at $6,677. 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.
