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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6237470430. Listed at 9 retailers as of October 30, 2026, with prices from $59,132 to $74,062, a $14,930 spread on the same certified stone. 77 Diamonds lists it at $74,062. 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.
