About this 3.09ct natural cushion diamond

This 3.09ct natural cushion sits in the three to five 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 6501380112. Listed at 21 retailers as of October 28, 2026, with prices from $64,560 to $119,444, a $54,883 spread on the same certified stone. MOH London lists it at $119,444. 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.
