About this 1.22ct natural cushion diamond

This 1.22ct 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 6552547980. Listed at 15 retailers as of October 29, 2026, with prices from £940 to £1,877, a £936 spread on the same certified stone. MOH London lists it at £1,877. 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.
