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 2307207778. Listed at 22 retailers as of October 31, 2026, with prices from HK$18,796 to HK$40,984, a HK$22,188 spread on the same certified stone. MOH London lists it at HK$40,984. 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.
