About this 0.89ct natural cushion diamond

This 0.89ct natural cushion sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5231993685. Listed at 14 retailers as of October 26, 2026, with prices from $896 to $2,136, a $1,240 spread on the same certified stone. MOH London lists it at $2,136. 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.
