About this 1.31ct natural cushion diamond

This 1.31ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2307170832. Listed at 7 retailers as of October 29, 2026, with prices from $6,136 to $12,121, a $5,984 spread on the same certified stone. MOH London lists it at $12,121. 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.
