About this 0.64ct natural cushion diamond

This 0.64ct natural cushion sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7391126787. Listed at 12 retailers as of October 29, 2026, with prices from £345 to £1,123, a £778 spread on the same certified stone. MOH London lists it at £1,123. 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.
