About this 2.5ct natural cushion diamond

This 2.5ct natural cushion sits in the two to three carat band, graded I 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 6247088621. Listed at 20 retailers as of November 1, 2026, with prices from £6,935 to £12,785, a £5,850 spread on the same certified stone. MOH London lists it at £12,785. 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.
