About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6542138710. Listed at 17 retailers as of November 2, 2026, with prices from €10,078 to €18,010, a €7,933 spread on the same certified stone. MOH London lists it at €18,010. 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.
