About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6405677842. Listed at 12 retailers as of November 6, 2026, with prices from $1,134 to $2,017, a $884 spread on the same certified stone. Yorxs lists it at $2,017. 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.
