About this 0.65ct natural cushion diamond

This 0.65ct natural cushion sits in the half to three-quarter 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 6521507027. Listed at 6 retailers as of October 29, 2026, with prices from $625 to $867, a $242 spread on the same certified stone. 77 Diamonds lists it at $867. 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.
