About this 3.21ct natural cushion diamond

This 3.21ct natural cushion sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7553351027. Listed at 4 retailers as of November 6, 2026, with prices from £35,659 to £44,798, a £9,139 spread on the same certified stone. 77 Diamonds lists it at £44,798. 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.
