About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1539449998. Listed at 14 retailers as of November 4, 2026, with prices from HK$10,432 to HK$23,948, a HK$13,517 spread on the same certified stone. MOH London lists it at HK$23,948. 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.
