About this 0.91ct natural cushion diamond

This 0.91ct natural cushion sits in the just-under-one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1186394878. Listed at 17 retailers as of October 31, 2026, with prices from £1,793 to £3,909, a £2,116 spread on the same certified stone. MOH London lists it at £3,909. 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.
