About this 0.56ct natural cushion diamond

This 0.56ct natural cushion sits in the half to three-quarter carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2517583302. Listed at 6 retailers as of October 29, 2026, with prices from £276 to £379, a £104 spread on the same certified stone. 77 Diamonds lists it at £379. 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.
