About this 1.2ct natural cushion diamond

This 1.2ct natural cushion sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7551099520. Listed at 11 retailers as of November 4, 2026, with prices from £1,367 to £3,141, a £1,773 spread on the same certified stone. MOH London lists it at £3,141. 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.
