About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6355575019. Listed at 9 retailers as of November 4, 2026, with prices from £2,027 to £4,043, a £2,016 spread on the same certified stone. MOH London lists it at £4,043. 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.
