About this 2.55ct natural cushion diamond

This 2.55ct natural cushion sits in the two to three carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5566515170. Listed at 7 retailers as of November 1, 2026, with prices from $16,060 to $25,314, a $9,254 spread on the same certified stone. MOH London lists it at $25,314. 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.
