About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556797520. Listed at 16 retailers as of November 5, 2026, with prices from HK$10,839 to HK$35,503, a HK$24,664 spread on the same certified stone. NZ Jewellers lists it at HK$35,503. 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.
