About this 1.2ct natural cushion diamond

This 1.2ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7556363723. Listed at 15 retailers as of November 4, 2026, with prices from £900 to £2,382, a £1,481 spread on the same certified stone. MOH London lists it at £2,382. 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.
