About this 3ct natural cushion diamond

This 3ct 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 2557425872. Listed at 3 retailers as of November 5, 2026, with prices from $35,096 to $41,600, a $6,504 spread on the same certified stone. Blue Nile lists it at $41,600. 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.
