About this 1.22ct natural cushion diamond

This 1.22ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2558490322. Listed at 18 retailers as of November 6, 2026, with prices from HK$15,346 to HK$35,574, a HK$20,228 spread on the same certified stone. MOH London lists it at HK$35,574. 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.
