About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded M 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 3555391514. Listed at 2 retailers as of November 4, 2026, with prices from $1,371 to $1,721, a $350 spread on the same certified stone. GemTrove lists it at $1,721. 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.
