About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7466185493. Listed at 11 retailers as of November 2, 2026, with prices from £643 to £1,405, a £762 spread on the same certified stone. MOH London lists it at £1,405. 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.
