About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2506498717. Listed at 13 retailers as of November 4, 2026, with prices from £1,830 to £3,615, a £1,785 spread on the same certified stone. MOH London lists it at £3,615. 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.
