About this 0.39ct natural cushion diamond

This 0.39ct natural cushion sits in the sub-half-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231778629. Listed at 4 retailers as of October 29, 2026, with prices from $750 to $1,405, a $654 spread on the same certified stone. MOH London lists it at $1,405. 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.
