About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded J 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 6422469009. Listed at 12 retailers as of November 1, 2026, with prices from HK$17,802 to HK$38,102, a HK$20,301 spread on the same certified stone. MOH London lists it at HK$38,102. 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.
