About this 0.31ct natural cushion diamond

This 0.31ct natural cushion sits in the sub-half-carat band, graded J 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 2526066350. Listed at 10 retailers as of October 26, 2026, with prices from $318 to $1,057, a $738 spread on the same certified stone. MOH London lists it at $1,057. 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.
