About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6552976335. Listed at 19 retailers as of October 30, 2026, with prices from €13,508 to €25,479, a €11,971 spread on the same certified stone. MOH London lists it at €25,479. 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.
