About this 1.2ct natural cushion diamond

This 1.2ct natural cushion sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2456824529. Listed at 16 retailers as of November 1, 2026, with prices from £1,722 to £3,718, a £1,995 spread on the same certified stone. MOH London lists it at £3,718. 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.
