About this 0.75ct natural cushion diamond

This 0.75ct natural cushion sits in the just-under-one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551393835. Listed at 4 retailers as of November 6, 2026, with prices from £435 to £530, a £95 spread on the same certified stone. 77 Diamonds lists it at £530. 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.
