About this 0.31ct natural cushion diamond

This 0.31ct natural cushion sits in the sub-half-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 6532073449. Listed at 4 retailers as of November 1, 2026, with prices from £338 to £603, a £265 spread on the same certified stone. MOH London lists it at £603. 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.
