About this 0.85ct natural cushion diamond

This 0.85ct 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 6561211355. Listed at 5 retailers as of November 2, 2026, with prices from $1,003 to $1,183, a $180 spread on the same certified stone. 77 Diamonds lists it at $1,183. 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.
