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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 2558118541. Listed at 17 retailers as of November 2, 2026, with prices from HK$8,433 to HK$20,046, a HK$11,613 spread on the same certified stone. MOH London lists it at HK$20,046. 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.
