About this 16.6ct natural cushion diamond

This 16.6ct natural cushion sits in the over five carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5232649608. Listed at 10 retailers as of October 30, 2026, with prices from £1,207,625 to £1,670,877, a £463,252 spread on the same certified stone. Ritani lists it at £1,670,877. 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.
