About this 1.23ct natural cushion diamond

This 1.23ct natural cushion sits in the classic one-carat band, graded G 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 6531645209. Listed at 18 retailers as of November 4, 2026, with prices from €1,215 to €2,791, a €1,577 spread on the same certified stone. MOH London lists it at €2,791. 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.
