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 SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2457556713. Listed at 16 retailers as of October 31, 2026, with prices from $3,393 to $7,392, a $3,999 spread on the same certified stone. MOH London lists it at $7,392. 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.
