About this 0.67ct natural cushion diamond

This 0.67ct natural cushion sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6237993667. Listed at 14 retailers as of November 1, 2026, with prices from £287 to £794, a £507 spread on the same certified stone. MOH London lists it at £794. 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.
