About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5373933999. Listed at 16 retailers as of November 6, 2026, with prices from $2,043 to $2,970, a $927 spread on the same certified stone. Yorxs lists it at $2,970. 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.
