About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5556434838. Listed at 18 retailers as of November 1, 2026, with prices from $2,128 to $4,790, a $2,662 spread on the same certified stone. MOH London lists it at $4,790. 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.
