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 standard cut grade stated by the retailer rather than the lab and certified by GIA 2397671802. Listed at 23 retailers as of October 29, 2026, with prices from £2,132 to £4,666, a £2,535 spread on the same certified stone. MOH London lists it at £4,666. 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.
