About this 3.5ct natural cushion diamond

This 3.5ct 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 2537496940. Listed at 7 retailers as of November 7, 2026, with prices from $49,452 to $64,120, a $14,668 spread on the same certified stone. Steven Stone lists it at $64,120. 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.
