About this 1.2ct natural cushion diamond

This 1.2ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5231978167. Listed at 16 retailers as of November 4, 2026, with prices from €1,882 to €4,489, a €2,607 spread on the same certified stone. MOH London lists it at €4,489. 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.
