About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6555159930. Listed at 18 retailers as of November 1, 2026, with prices from £13,135 to £23,954, a £10,818 spread on the same certified stone. MOH London lists it at £23,954. 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.
