About this 1.28ct natural cushion diamond

This 1.28ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1246065633. Listed at 5 retailers as of October 31, 2026, with prices from £6,646 to £8,746, a £2,100 spread on the same certified stone. Cape Diamonds lists it at £8,746. 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.
