About this 1.21ct natural radiant diamond

This 1.21ct natural radiant sits in the classic one-carat band, graded G colour (near-colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2277801455. Listed at 4 retailers as of November 2, 2026, with prices from HK$17,889 to HK$22,911, a HK$5,022 spread on the same certified stone. Yorxs lists it at HK$22,911. 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.
