About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded I 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 1563405840. Listed at 7 retailers as of November 1, 2026, with prices from $21,434 to $33,316, a $11,882 spread on the same certified stone. MOH London lists it at $33,316. 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.
