About this 0.79ct natural cushion diamond

This 0.79ct natural cushion sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1567114728. Listed at 7 retailers as of October 28, 2026, with prices from £649 to £935, a £286 spread on the same certified stone. GemTrove lists it at £935. 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.
