About this 3.51ct natural cushion diamond

This 3.51ct natural cushion sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included) and certified by GIA. Listed at 3 retailers as of November 5, 2026, with a relatively tight 14% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
