About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2547599981. Listed at 19 retailers as of October 29, 2026, with prices from $13,187 to $23,286, a $10,099 spread on the same certified stone. MOH London lists it at $23,286. 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.
