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 6561550102. Listed at 13 retailers as of November 4, 2026, with prices from $40,299 to $72,823, a $32,523 spread on the same certified stone. MOH London lists it at $72,823. 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.
