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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6531505758. Listed at 11 retailers as of October 28, 2026, with prices from £467 to £853, a £386 spread on the same certified stone. GemTrove lists it at £853. 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.
