About this 3.34ct natural cushion diamond

This 3.34ct natural cushion sits in the three to five carat band, graded F 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 2557434217. Listed at 3 retailers as of October 31, 2026, with prices from £20,173 to £42,982, a £22,809 spread on the same certified stone. Blue Nile lists it at £42,982. 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.
