About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5543757935. Listed at 7 retailers as of November 4, 2026, with prices from $17,548 to $25,676, a $8,128 spread on the same certified stone. MOH London lists it at $25,676. 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.
