About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1545703092. Listed at 12 retailers as of November 2, 2026, with prices from €18,216 to €29,965, a €11,749 spread on the same certified stone. MOH London lists it at €29,965. 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.
