About this 0.8ct natural cushion diamond

This 0.8ct natural cushion sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1285830747. Listed at 11 retailers as of November 4, 2026, with prices from £740 to £1,537, a £797 spread on the same certified stone. MOH London lists it at £1,537. 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.
