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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 2434972267. Listed at 14 retailers as of October 28, 2026, with prices from £1,543 to £3,591, a £2,049 spread on the same certified stone. Moon Ocean lists it at £3,591. 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.
