About this 0.73ct natural cushion diamond

This 0.73ct 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 6565163046. Listed at 4 retailers as of November 4, 2026, with prices from £478 to £590, a £112 spread on the same certified stone. 77 Diamonds lists it at £590. 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.
