About this 5.16ct natural cushion diamond

This 5.16ct natural cushion sits in the over five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231559833. Listed at 10 retailers as of October 29, 2026, with prices from $111,990 to $183,791, a $71,801 spread on the same certified stone. MOH London lists it at $183,791. 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.
