About this 0.31ct natural cushion diamond

This 0.31ct natural cushion sits in the sub-half-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2556708256. Listed at 9 retailers as of November 2, 2026, with prices from $371 to $1,200, a $828 spread on the same certified stone. MOH London lists it at $1,200. 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.
