About this 0.31ct natural cushion diamond

This 0.31ct natural cushion sits in the sub-half-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3555708794. Listed at 10 retailers as of October 29, 2026, with prices from $517 to $1,652, a $1,136 spread on the same certified stone. MOH London lists it at $1,652. 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.
