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 October 30, 2026, with prices from $34,198 to $40,115, a $5,917 spread on the same certified stone. Blue Nile lists it at $40,115. 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.
