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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1458362282. Listed at 20 retailers as of November 4, 2026, with prices from $3,131 to $6,779, a $3,648 spread on the same certified stone. MOH London lists it at $6,779. 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.
