About this 0.85ct natural cushion diamond

This 0.85ct natural cushion sits in the just-under-one-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 6545782099. Listed at 6 retailers as of October 28, 2026, with prices from £545 to £897, a £352 spread on the same certified stone. GemTrove lists it at £897. 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.
