About this 0.91ct natural cushion diamond

This 0.91ct natural cushion sits in the just-under-one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2141711954. Listed at 9 retailers as of November 1, 2026, with prices from £1,739 to £2,684, a £945 spread on the same certified stone. 77 Diamonds lists it at £2,684. 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.
