About this 1.21ct natural radiant diamond

This 1.21ct natural radiant 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 1206694754. Listed at 11 retailers as of October 31, 2026, with prices from HK$23,603 to HK$33,850, a HK$10,247 spread on the same certified stone. Yorxs lists it at HK$33,850. 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.
