About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6371935777. Listed at 12 retailers as of October 29, 2026, with prices from $3,647 to $5,036, a $1,389 spread on the same certified stone. Yorxs lists it at $5,036. 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.
