About this 1.21ct natural radiant diamond

This 1.21ct natural radiant sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7561587839. Listed at 8 retailers as of November 5, 2026, with prices from HK$19,766 to HK$47,338, a HK$27,572 spread on the same certified stone. NZ Jewellers lists it at HK$47,338. 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.
