About this 1.23ct natural cushion diamond

This 1.23ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7318471513. Listed at 10 retailers as of November 1, 2026, with prices from $2,373 to $4,957, a $2,584 spread on the same certified stone. MOH London lists it at $4,957. 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.
