About this 1.2ct natural cushion diamond

This 1.2ct 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 1323427541. Listed at 12 retailers as of November 4, 2026, with prices from $2,384 to $5,608, a $3,224 spread on the same certified stone. MOH London lists it at $5,608. 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.
