About this 0.87ct natural cushion diamond

This 0.87ct 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 6172390537. Listed at 20 retailers as of October 28, 2026, with prices from $3,744 to $8,201, a $4,457 spread on the same certified stone. MOH London lists it at $8,201. 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.
